Sdr
Software defined radios (SDR) use software to control radio functions like filtering, frequency coverage, and modulation modes. This flexibility allows SDRs to change how they operate through software updates rather than hardware changes. Key benefits are low cost since most functions are done in software, and versatility to support different communication standards worldwide. The goal of SDR is to have a single transceiver that can work as different devices like phones or radios through software reconfiguration alone. Hobbyists can use inexpensive SDRs and decoding software to track ships by receiving automatic identification system signals.
Software defined radio
This document discusses software defined radio (SDR) technology. SDR uses software modules running on generic hardware like DSPs and microprocessors to implement radio functions rather than using dedicated hardware components. This allows radios to have their functionality redefined or upgraded through changes to its software. The document outlines the architecture of SDR systems and provides examples of SDR applications in areas like public safety, military uses, and commercial devices. It also discusses benefits such as flexibility and interoperability as well as challenges related to hardware limitations and software complexity. The future scope of SDR is seen to include adaptive radios and cognitive radios that can dynamically change their transmission behavior.
Sdr the future of radio
SDR and cognitive radio technologies will enable more flexible use of radio spectrum and facilitate interoperability between different communication standards. Key drivers include the need for first responder communications during emergencies, the increasing number of wireless standards, and the scarce availability of radio spectrum. SDR allows communication standards and functionality to be reconfigured through software downloads. Future technologies like improved ADCs, DSPs, and cognitive abilities will advance SDR and spectrum sensing capabilities. Both military and commercial applications are expected to benefit from SDR and cognitive radio.
Software defined radio
Software defined radio uses software to control radio functions like modulation and demodulation rather than using dedicated hardware components. It allows a software radio to function as different types of radios through software changes alone. This reduces costs compared to hardware radios and makes radios more flexible and upgradable.

Moving target indicator radar (mti)
The document discusses radar clutter and techniques for eliminating it. Clutter refers to radar returns from stationary objects that are not of interest. Two main techniques for reducing clutter are discussed: moving target indication (MTI) radar, which detects Doppler shifts from moving targets, and delay line cancellers/transversal filters, which cancel out stationary clutter returns. MTI radars preserve phase coherence to differentiate stationary vs moving targets, while cancellers/filters use weighted signal delays and summing to attenuate clutter signals.

Universal software defined radio development platform
Award winning presentation at a NATO RTO IST symposium in 2006 on Universal Software Defined Radio (SDR) Development Platform and its use for prototyping radar system and spectrum monitoring receiver. Till this time I made several presentations on the topic, but this is the original version from 2006.
Hardware Accelerated Software Defined Radio
Advanced 5G wireless infrastructure should support any-to-any connectivity between densely arranged smart objects that form the emerging paradigm known as the Internet of Everything (IoE). While traditional wireless networks enable communication between devices using a single technology, 5G networks will need to support seamless connectivity between heterogeneous wireless objects, and consequently enable the proliferation of IoE networks. To tackle the complexity and versatility of the future IoE networks, 5G has to guarantee optimal usage of both spectrum and energy resources and further support technology-agnostic connectivity between objects. This can be realized by combining intelligent network control with adaptive software-defined air interfaces. In order to achieve this, current radio technology paradigms like Cloud RAN and Software Defined Radio (SDR) utilize centralized baseband signal processing mainly performed in software. With traditional SDR platforms, composed of separate radio and host commodity computer units, computationally-intensive signal processing algorithms and high-throughput connectivity between processing units are hard to realize. In addition, significant power consumption and large form factor may preclude any real-life deployment of such systems. On the other hand, modern hybrid FPGA technology tightly couples a FPGA fabric with hard core CPU on a single chip. This provides opportunities for implementing air interfaces based on hardware/software co-processing, resulting in increased processing throughput, reduced form factor and power consumption, while at the same time preserving flexibility. This paper examines how hybrid FPGAs can be combined with novel ideas such as RF Network-on-Chip (RFNoC) and partial reconfiguration, to form a flexible and compact platform for implementing low-power adaptive air interfaces. The proposed platform merges software and hardware processing units of SDR systems on a single chip. Therefore, it can provide interfaces for on-the-fly composition and reconfiguration of software and hardware radio modules. The resulting system enables the abstraction of air interfaces, where each access technology is composed of a structured sequence of modular radio processing units.

Amateur radio, also known as ham radio, allows for non-commercial wireless communication between operators. It uses radio frequencies to allow for message exchange, experimentation, recreation, contesting and emergency communication. Key frequencies used are short wave bands between 1.8-30 MHz and VHF bands between 144-146 MHz. Ham radio operators communicate through various modes including Morse code, analog voice modes like AM and FM, digital text modes, and image transmission modes. Common equipment used includes HF and VHF transceivers, dipole antennas, and repeaters which retransmit weak signals at higher power to increase their coverage area.

Ed Swindle - MOD - Military use of the Band
This document provides information on spectrum occupancy from 2 MHz to 15 GHz, showing which frequency bands are used by various civil and military applications. It includes a chart displaying frequency ranges along the x-axis and applications along the y-axis to indicate what uses each band. The document also discusses considerations for sharing the 5 GHz band, noting it is reserved for exclusive military use from 5250-5850 MHz in the UK. Military systems like radars, networks, and weapon systems operate in this band, which is also designated as a NATO Class A essential band. While open to sharing initiatives, the military would need independent verification that sharing with WiFi/RLAN would not impact operations.

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).
