Investigation of TV White Space for Maximum Spectrum Utilization in a Cellula...Onyebuchi nosiri
Abstract— The shortage of spectrum resource availability in wireless communication network due to the rapid increase in the number of subscribers and multimedia applications has given rise to the need for effective spectrum utilization of the licensed spectrum. Cognitive Radio Technology (CRT) was adopted for the system analysis due to its dynamism in accommodating both licensed and unlicensed users within a particular spectrum band. The study framework comprised television station channels in Owerri and its environs and Mobile Telecommunication Networks (MTN) in Owerri- the capital of Imo State, Nigeria as the license and unlicensed users respectively. An outdoor twenty-four hour spectrum occupancy measurement was carried out in the frequency bands of the licensed networks using 240-960 MHz Radio Frequency Spectrum analyzer to determine the spectral usage of the licensed user. A threshold of -95 dB was used to determine the presence of the licensed users. From the results obtained, it was observed that 60.7% of the spectrum band covered was unoccupied, 31.5% was not fully occupied while 7.9% was fully occupied. Energy Detection spectrum approach was implemented by the unlicensed users for easy determination of the spectrum status and resource management. The research therefore determines the status of Radio Frequency (RF) Spectrum receivable in Owerri and its environs and proffer measures deployable in harnessing the unused RF resources using CRT.

This study was carried out to investigate the spectrum utilization of the licensed Radio Frequency (RF) spectrum in Rumuokwuta, Port Harcourt. An outdoor measurement of spectrum occupancy was carried out in a high-rise building situated at Rumuokwuta urban area in Port Harcourt, Nigeria using RF explorer spectrum analyzer and a personal computer laptop system. Spectrum activities in the band of 240-960 MHz were monitored for 24 hours. The frequency band was subdivided into 24 sub bands each with a span size of 30 MHz. Scanning of bands was made efficient using a python script that scans a range, analyzed the frequencies and signal strengths for 112 data points, saves data in CSV file format, scans the next range until the 24 ranges were scanned. The process was repeated to achieve 15 iterations. With a noise floor of - 110dBm, a threshold of -95dBm was used to determine the presence of signal, hence the spectrum occupancy of measured bands. Results showed that out of the 24 investigated sub bands; only one band was completely occupied with spectrum occupancy of 100%. 12 bands were partially occupied while 11 were completely free. The average spectrum occupancy for the whole band was obtained as 11.64%. This showed good location for dynamic spectrum access and cognitive radio deployment, especially in Television White Space (TVWS).
GNSS interference reduction method for CORS site planningTELKOMNIKA JOURNAL
Precision, Navigation, and Timing (PNT) system based on Global Navigation Satellite System
(GNSS) becomes significant in the air, land, and sea traffic management. Integrity of GNSS is significant to
provide a reliable real time PNT system such as CORS (Continuously Operating Reference Stations).
GNSS Interference due to intentional or unintentional surrounding signal source may decrease the integrity
of GNSS signal. Monitoring and identification of potential GNSS interference sources in the surrounding
environment of CORS is significant. This paper proposed a methodology to reduce potential GNSS
interference in a planned CORS site by first simulating the radiation pattern of potential source of
interference to GNSS signal in the planned CORS sites. Thereafter ambient noise levels in the location of
CORS may be measured to provide a reference point for analyzing the other potential sources of
interferences. Based on these results, optimal location of CORS is chosen with the lowest possible
unintentional interference signal from their surrounding. Measurement has been conducted in the location
of CORS owned by BIG (Indonesian Agency for Geospatial Information), which is located in the rooftop of
a building neara telecommunication tower.This method is necessary for CORS site planning to reduce

Telecommunication frequency band spectrum occupancy in kampala ugandaeSAT Journals
Abstract The Effective utilization of the radiofrequency electromagnetic spectrum is paramount for wireless communication systems especially in telecommunication. This paper presents measurements and analysis of spectrum occupancy in the telecommunication frequency bands performed in Kampala, Uganda in March 2015. The telecommunication bands considered in this study are GSM900, GSM1800, UMTS2100 and LTE2600. Occupancy measurements have been carried out in an outdoor setting using the Aaronia Hyperlog 70600 antenna and the Spectran HF-6065 V4.The analysis shows that the licensed telecommunication spectrum bands are not fully utilized. Highest spectrum occupancy of 52.4% was observed in the GSM900 Downlink telecommunication band while the lowest occupancy of approximately 0% was observed in the LTE2600 band. Key words: spectrum occupancy, wireless telecommunication, Duty cycle, Threshold
Ultrawideband is a wireless radio technology originally developed for secure military communications and

802.11b. It can be used for transferring digital content between devices in different entertainment and
computing clusters in the home, such as digital video recorders, set-top boxes, televisions and PCs. UWB is
designed to replace cables with short-range, wireless connections, but it offers the much higher bandwidth
needed to support multimedia data streams at very low power levels. And because UWB can communicate both
relative distance and position, it can be used for tracking equipment, containers or other objects

Next generation optical networks will evolve from static to dynamically reconfigurable architectures to meet the increasing bandwidth and service requirements. When considering signal quality in static networks, it is sufficient to monitor a single channel in a WDM system, since all channels travel through the same fixed path degrading the signal quality uniformly due to link mismatch. However, in dynamic networks, each channel will traverse a unique path through the network thus the channels arriving at the monitoring point will, in general, exhibit different quality signals. Therefore, in a dynamic network it is necessary to monitor all channels individually to quantify the degradation, without the requirement of knowing the data path history. Thus optical performance monitoring (OPM) is essential in building a reliable, high-capacity, and service-differentiation enabled all optical network.

Wavelet-based sensing technique in cognitive radio networkTELKOMNIKA JOURNAL
Cognitive radio is a smart radio that can change its transmitter parameter based on interaction with the environment in which it operates. The demand for frequency spectrum is growing due to a big data issue as many Internet of Things (IoT) devices are in the network. Based on previous research, most frequency spectrum was used, but some spectrums were not used, called spectrum hole. Energy detection is one of the spectrum sensing methods that has been frequently used since it is easy to use and does not require license users to have any prior signal understanding. But this technique is incapable of detecting at low signal-to-noise ratio (SNR) levels. Therefore, the wavelet-based sensing is proposed to overcome this issue and detect spectrum holes. The main objective of this work is to evaluate the performance of wavelet-based sensing and compare it with the energy detection technique. The findings show that the percentage of detection in wavelet-based sensing is 83% higher than energy detection performance. This result indicates that the wavelet-based sensing has higher precision in detection and the interference towards primary user can be decreased.

From an industrial viewpoint also, the advanced signal processing technology cannot only dramatically increase the wireless system capacity but can also improve the communication quality including the reduction of all types of interference. The present paper deals with simulation model of square root raised cosine pulse shaping filter for WCDMA with different parameters of the filter at 5Mhz.The present paper deals with study of Simulation Parameters (Number of Bits, Number of Errors) of Pulse Shaping FIR Filter at different value of group delay(2,4,6,8) to the calculate BER for WCDMA.
With cloud computing, users can remotely store their data into the cloud and use on-demand high-quality applications. Data outsourcing: users are relieved from the burden of data storage and maintenance When users put their data (of large size) on the cloud, the data integrity protection is challenging enabling public audit for cloud data storage security is important Users can ask an external audit party to check the integrity of their outsourced data. Purpose of developing data security for data possession at un-trusted cloud storage servers we are often limited by the resources at the cloud server as well as at the client. Given that the data sizes are large and are stored at remote servers, accessing the entire file can be expensive in input output costs to the storage server. Also transmitting the file across the network to the client can consume heavy bandwidths. Since growth in storage capacity has far outpaced the growth in data access as well as network bandwidth, accessing and transmitting the entire archive even occasionally greatly limits the scalability of the network resources. Furthermore, the input output to establish the data proof interferes with the on-demand bandwidth of the server used for normal storage and retrieving purpose. The Third Party Auditor is a respective person to manage the remote data in a global manner.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Abstract: - Spectrum Monitoring is, besides Spectrum Planning and Licensing, one of the key
elements in spectrum management process. Monitoring is not only solving interference problems but
also tasked with for instance:
Checking license parameters, e.g. field strength and band width (remote inspection)
Comparing predicted and measured values
Identifying illegal use
Supporting preparation for WRC
Quick overview of the spectrum
Reframing
Detecting White Spaces, etc
Frequency Planning and Licensing provide the theoretical (calculated) occupancy. Monitoring provides the
real (automatically or manual measured) occupancy.The smaller the difference between theoretical and real
occupancy, the better the quality of the overall spectrum management process.

1. INTRODUCTION
Signal being transmitted, receiver and travel at least significant portion of their path in free space this
clearly an essential characteristic in certain application such as mobile phone, satellite communication,
broadcasting and radio navigation.
In other application such as fixed links and fixed wireless (FWA), it provides a key advantage the
avoidance of upfront cost of laying transmission lines.
The main disadvantage however is that transmission over free space means that stray signals from one
radio communication system can easily interfere with the proper reception of another. Interference is
unavoidable and ever present.
The impact of excessive interference ranges from simple inconvenience to individual users to, on
occasions, the undermining of the viability of networks suffering interference. At the very extreme, it can
have safety of life implications, for example where radio systems used by the emergency services suffer
interference. Furthermore radio signals do not respect national borders. Thus, if not properly managed,
signals emanating from one country can unduly interference with system in other countries.
This propensity to interfere, locally and regionally, is the key factor rendering the radio spectrum a
resource. National regulatory authorities (NRAs) throughout the world have therefore regarded it as one of
their central duties to ensure both an acceptable interference environment as well as maximizing the
(technically) efficient use of the available spectrum.
This has resulted in implication of international regulation and technical considerations on market

mechanisms in spectrum management , a significantly regulated environment in radio communications,
with the vast majority of NRAs in the world retaining close control on deciding both the type of permitted
services and which organizations should be licensed to operate in a given trencher of spectrum.
So, we need radio monitoring system that can manage radio efficiently and measure radio quality
accurately through spectrum analysis for protecting wireless equipment and maintaining quality level of
radio, communication service. Also, since conventional radio monitoring system can't measure frequency
efficient use investigation and spectrum analysis that is equivalent to occupied bandwidth measurement,
broadband frequency measurement, high-speed spectrum measurement, unwanted electromagnetic signal in
radio quality measurement, radio monitoring system need to be developed for executing efficient radio
monitoring work with reservation measurement function and automatic result storage function that can be
done accurate radio measurement of local operators.
I. RADIO MONITORING SYSTEM
We constitute Database and remote control system for save and analysis of measurement data. We use a
normal receiver, DSP for spectrum processing with high velocity, control PC to solve the problem of
Previous Radio Monitoring System and express efficient radio monitoring system for new communication
environment.
General receiver and DSP (Digital Signal Processor) with spectrum analysis equipment based on software
defined radio technology design and execute measured algorithm, and analog and digital signal of on-air,
that is, mobile base station permitted between 20MHz and 3GHz, FM radio broadcasting station, CDMA,
DMB is channel power, frequency deviation and declination,
occupied bandwidth and using this through spectrum analysis can function accurate and efficient analysis
ever. Thus, only future program upgrade without hardware exchange can execute multiple measurement
function, also future cost reduction and conventional receiver is designed for processing broadband/
narrowband signal.

Radio quality measurement has direct measurement mode, channel measurement mode, maximum received
azimuth measurement mode. Direct measurement mode measuring one frequency generates result about
frequency deviation, shift, occupied bandwidth, signal level, in-depth modulation of AM and stores
spectrum data, voice file. Channel measurement mode measures received frequency that is over threshold
level sequentially, and measured result is identical direct measurement mode. Maximum received azimuth
measurement mode turn around direct antenna with three hundred and sixty degree, and measured signal
level about frequency, so direct antenna utilize radio quality measurement using measured result of optimal
azimuth.

Unwanted electromagnetic measurement has spurious measurement mode and harmonic measurement
mode. Spurious measurement mode measures spurious generation about spurious signal power and mask
invasion of analog broadcasting frequency occasionally.

V. ILLEGAL RADIO EXPLORATION
The illegal radio exploration exposes an illegal radio station using without permission in 20 MHz ~ 3.2
GHz frequency band. It explores all frequency bands by channel or band scan. The signal exceeded
threshold level recorded by demodulation receiver and utilized to an evidence data.
The channel measurement mode scans the maximum 1000 channels using the Memory Scan Mode
(MSCAN mode) of a receiver and detects an illegal signal over the threshold level. The frequency of used
channel file is the frequency judged illegally. The band measurement mode uses Frequency Scan Mode
(FSCAN mode) of a receiver. It scan maximum one hundred thousand bands on a frequency interval of the
legal step size in the set frequency and detects an
illegal signal over the threshold level. This mode references a database in advance and don't measure a
permitted frequency band..

detected signal over the threshold level, this mode demodulates the voice automatically. If the AFC (Auto
Frequency Control) frequency is a non-permission frequency, it displays the measure frequency, AFC
frequency, bandwidth, modulation type, signal level, detecting time and voice file name (.723). And the
measurement results stored in database, the voice file stored in the file server
