Abstract: The wireless channel is central within this context, thus estimating the channel is the key to make CR operational, taking in consideration that the transmission-reception technology is available. In this thesis, we design a MIMO system using OFDM modulation technology to transmit and receive two signals over the mobile wireless channel. First formulate the pilot design as a new optimization problem. We use MIMO concept to enhance system capacity and robustness of the wireless transmission. In Multi-Input Multi-Output (MIMO) based cognitive radio (CR) systems, with the increasing demand for data rate and reliability in Wireless communicationsand devices, several issues become very important like bandwidth efficiency, quality of service and radio coverage. In this new scheme, adaptive arrays are group-selected in the spatial domain. Simulation shows that the proposed system can get significant performance improvements over the conventional array based OFDM systems over frequency-selective multipath fading channels with cognitive radio (CR) system. Keywords: Cognitive radios, MIMO, OFDM, and Joint transmit and receive group selected arrays.

This document analyzes the capacity of MIMO wireless channels when accounting for impairments from physical transceiver hardware limitations. It is shown that when including the effects of transceiver impairments like non-linearities, phase noise, and quantization noise, the capacity of MIMO channels reaches a finite limit as SNR increases, rather than increasing without bound. This results in a zero multiplexing gain, unlike the ideal case without impairments. However, the relative capacity increase from MIMO over single-antenna channels remains at least as large when including impairments. Various figures are presented showing the capacity and multiplexing gain for different channel models and transceiver configurations. The document concludes by stating the analysis provides insights into understanding

This document describes a Simulink-based simulation model for Quadrature Amplitude Modulation (QAM) systems. The model simulates 4-QAM, 16-QAM, and 64-QAM and calculates the error rate for each at varying signal-to-noise ratios. The simulation results show that higher order QAM techniques have higher error rates due to symbol points being closer together. However, they also provide higher data transmission rates. The model can be used not only to evaluate QAM for adaptive modulation but also to simulate other digital modulation techniques.
Designing and Performance Evaluation of 64 QAM OFDM SystemIOSR Journals
Abstract (11Bold) : — In this report, the performance analysis of 64 QAM-OFDM wireless communication
systems affected by AWGN in terms of Symbol Error Rate and Throughput is addressed. 64 QAM (64 ary
Quadrature Amplitude Modulation) is the one of the effective digital modulation technique as it is more power
efficient for larger values of M(64). The MATLAB script based model of the 64 QAM-OFDM system with
normal AWGN channel and Rayleigh fading channel has been made for study error performance and
throughput under different channel conditions. This simulated model maximizes the system throughput in the
presence of narrowband interference, while guaranteeing a SER below a predefined threshold. The SER
calculation is accomplished by means of modelling the decision variable at the receiver as a particular case of
quadratic form D in complex Gaussian random variables. Lastly comparative study of SER performance of 64
QAM-OFDM simulated & 64 QAM-OFDM theoretical under AWGN channel has been given. Also
performance of the system is given in terms of throughput (received bits/ofm symbol) is given in a plot for
different SNR. Keywords (11Bold) –64 QAM, BPSK, OFDM, PDF, SNR.

Modulation Applications
There are several variances between analog and digital transmission technologies and it is crucial to comprehend how conversions between the two technologies occur. An analog signal is describe as being constantly variable along amplitudes and frequencies. On the other hand, digital transmissions is very different from its analog transmissions. One difference is the signal is considerable simpler. Rather than being constantly a variable wave form, it is a series of separate pulses that represent one and zeros. As for example, each computer utilizes a coding scheme that outlines what arrangement of ones and zeros create all characters in a character set, which includes upper and lower case letters, special characters, and keyboard control functions (Goleniewski, 2015). Furthermore, there are many technologies covert the two signals on both directions, meaning analog-to-digital and digital-to-analog. This is the case of a two converters DAC and ADC technologies. An ADC is the device that coverts or transforms a continuous physical quantity (voltage) to a digital number that presents the quantity’s amplitude. ADCs covers digital data into an analog signal such as a current or voltage. These converters are found on most electronic devices that plug to the electric outlet. They are microchips integrated on the circuit board of the electronic device.
There are several types of modulation applications. These applications are amplitude, frequency, phase and QAM modulation. They all serve different but important purposes. Along with these purposes there are also advantages and disadvantages.
Amplitude modulation (AM) is used in a variety of applications. Although use of the modulation is not relied upon currently as it was used in the past, you can still find it in its basic form. When an AM modulated signal is created, the amplitude of the signal is varied in line with the variations in intensity of the sound wave. AM is the most straightforward way of modulating a signal. Some of the advantages are, it is simple to implement, an AM signal is efficient in terms of its power usage, and it can be demodulated using a circuit consisting of a very few components. Disadvantages are AM signals are prone to high levels of noise because most noise is amplitude based and AM detectors are sensitive to it.
Frequency Modulation (FM) is used in a wide variety or radio communication applications from broadcasting, two way radio communications links, and mobile radio communications. It possesses many advantages over AM. For example, it is resilient to noise. FM that has been utilized by the broadcasting industry is the reduction in noise. FM Does not require linear amplifiers in the transmitter. Disadvantages are it requires more complicated demodulator. Some other modes have higher data spectral efficiency.
Phase Modulation (PM) is a form of modulati ...
Bit Error Rate Assessment of Digital Modulation Schemes on Additive White Gau...inventionjournals
This document evaluates the performance of three digital modulation schemes (16-QAM, 64-QAM, and 16-DPSK) in terms of bit error rate on different channel models (AWGN, Rician fading, and Rayleigh fading). Simulation results show that 16-QAM has better performance with lower bit error rates compared to 64-QAM and 16-DPSK across all channel models. 16-QAM modulation is more spectrally efficient than other schemes and can send more bits per symbol. The document provides background on digital modulation techniques, channel models, and simulations conducted in MATLAB to compare the performance of the modulation schemes.
This document provides an overview of telecommunication systems and communication engineering. It discusses analog and digital signals, different modulation techniques used in communication systems including amplitude modulation and frequency modulation. Key aspects covered include:
- Analog signals are continuous over time and amplitude while digital signals involve quantization.
- A basic communication system includes a source, transmitter to convert the signal to a transmission format, a channel with noise, a receiver to decode the signal, and a destination.
- Modulation involves varying properties of a carrier signal like amplitude, frequency, or phase to transmit a message signal over a channel.
- Common modulation techniques are amplitude modulation which varies signal strength, and frequency modulation which varies carrier frequency.
This document provides an overview of telecommunication systems and communication engineering. It discusses analog and digital signals, the components of a basic communication system including the source, transmitter, channel, receiver and destination.

It also includes block diagrams of wireless communication systems and their components such as the transmitter, encoder, noisy channel, decoder and receiver.
This document provides an overview of equalization and diversity techniques used in mobile communication systems. It discusses how equalization is used to compensate for intersymbol interference caused by multipath fading. Linear equalizers aim to minimize mean square error, while nonlinear equalizers also use decision feedback. Common equalizer structures include transversal filters adapted using algorithms like LMS or RLS. Diversity techniques like spatial or frequency diversity compensate for fading by combining signals from multiple antennas or frequency bands. Channel coding adds redundancy to improve link performance in the presence of errors.
This document discusses the design of terrestrial microwave links. It begins with an introduction to microwave links and their basic components - transmitters, towers, antennas, and receivers. Antennas must have line-of-sight between sites. The document then covers topics like frequency standards, polarization, antenna types, link budgets, and operating frequencies. It provides block diagrams of transmitter and receiver base stations. Key components like mixers, filters, amplifiers and their functions are described. Signal spreading in W-CDMA systems is also explained. Technical characteristics of microwave point-to-point links are outlined.
The document discusses smart antennas in 3G networks. It provides an introduction to smart antennas, how they form adaptive beams to improve communication links. Smart antennas can increase network capacity and coverage by directing beams toward desired users and nulling interference. This is done through algorithms that calculate antenna weights to maximize signal strength and minimize interference using techniques like beamforming and null steering. Smart antennas allow strategies like interference reduction, rejection, and spatial division multiple access to improve system performance. When applied in 3G base stations, smart antennas can form multiple beams to cover cells, track users to adaptively change beam patterns, and null interference to further increase capacity and coverage for mobile users.

This document discusses methods for improving spectral efficiency in communication systems. It provides information on different modulation techniques and factors that influence spectral efficiency, such as signal-to-noise ratio, bandwidth efficiency, forward error correction, data compression, and MIMO. It also describes how modulation and demodulation are implemented using software-defined radios and digital signal processing. The pursuit of greater spectral efficiency is important given the finite amount of radio spectrum and growing demand for wireless services.
This document discusses beamforming and the eight transmission modes in LTE Release 9. It begins with introductions to MIMO technology and beamforming basics. It then explains the eight transmission modes, including single transmit antenna mode, transmit diversity, open and closed loop spatial multiplexing, multi-user MIMO, and two beamforming modes that use UE-specific reference signals. Key aspects of LTE such as physical channels and the reference signal structure are also summarized.
The document discusses channel estimation techniques for wireless communication systems. It describes that channel estimation is important for mobile wireless networks as the channel changes over time due to movement. It summarizes that channel estimation algorithms allow the receiver to approximate the time-varying channel impulse response. The document then compares two popular channel estimation algorithms - LMS and RLS. LMS uses estimates of the gradient vector to iteratively minimize the mean square error, while RLS recursively finds filter coefficients to minimize a weighted linear least squares cost function.
Orthogonal frequency-division multiplexing (OFDM)
[1] is a method of encoding digital data on multiple carrier
frequencies. OFDM[1] has developed into a popular scheme
for wideband digital communication, whether wireless or
over copper wires, used in applications such as digital television
and audio broadcasting, DSL Internet access, wireless networks,
powerline networks, and 4G mobile communications. In the
Several wireless standards such as IEEE 802.11a[2] and
HiperLAN2[3].The orthogonality of the subcarriers is no longer
maintained which results in ICI (Inter carrier Interference)[4]
.ICI reduction techniques achieve a better SNR and BER in
OFDM at zero phase noise variance . This technique will use a
large number of closely spaced orthogonal subcarriers to avoid
phase noise. It provides high data rates with sufficient robustness
to radio channel damages. A major problem in OFDM is carrier
frequency offset error between the transmitted and received
signals. Due to this the orthogonality of the subcarriers is no
longer maintained which results in ICI (Inter carrier
Interference). In this paper, we used the ICI self-cancellation
technique and reduced the ICI and improved the BER and SNR
we are also calculate the SNR=15db and 20db at different phase
noise variance.
