With the growing complexity of personal mobile communication systems demanding higher data-rates and high levels of integration using low-cost CMOS technology, overall system performance has become more sensitive to RF analog front-end impairments. Designing integrated transceivers requires a thorough understanding of the whole transceiver chain including RF analog front-end and digital baseband. Communication system engineers have to include RF analog imperfections in their simulation benches in order to study and quantify their impact on the system performance. Here the author explores key RF analog impairments in a transceiver and demonstrates how to model their impact from a communication system design view-point. He discusses the design aspects of the front end of transceivers (both receivers and transmitters) and provides the reader with a way to optimize a complex mixed-signal platform by taking into account the characteristics of the RF/analog front-end. Key features of this book include: Practical examples illustrated by system simulation results based on WiFi and mobile WiMAX OFDM transceivers An overview of the digital estimation and compensation of the RF analog impairments such as power amplifier distortion, quadrature imbalance, and carrier and sampling frequency offsets An exposition of the challenges involved in the design of both RF analog circuits and DSP communication circuits in deep submicron CMOS technology MATLAB® codes for RF analog impairments models hosted on the companion website Uniquely the book bridges the gap between RFIC design specification needs and communication systems simulation, offering readers RF analog impairments modeling knowledge and a comprehensive approach to unifying theory and practice in system modelling. It is of great value to communication systems and DSP engineers and graduate students who design communication processing engines, RF/analog systems and IC design engineers involved in the design of communication platforms.

This is one of the first books on the emerging research topic of digital compensation of RF imperfections. The book presents a new multidisciplinary vision on the design of wireless communication systems. In this approach the imperfections of the RF front-ends are accepted and digital signal processing algorithms are designed to suppress their impact on system performance. The book focuses on multiple-antenna orthogonal frequency division multiplexing (MIMO OFDM).

A practical software radio system (SDR) typically suffers from a number of impairments in its migration from a baseband signal at the transmitter to its replication at the receiver. This gives rise to error generation and degradation in overall system performance. Analog impairments at the intermediate frequency (IF) can have many of the same issues as radio frequency (RF) signals and they also include modulator and demodulator mismatches between the I and Q-channels. These RF and analog impairments are not confined to SDR systems but may be found in any digital radio system. The fact that the SDR uses such a large portion of digital logic and direct conversion receiver (DSP) introduces additional impairment concerns that may not be found in a traditional radio design. The digital radio receiver's main function is to extract the variable RF signals in the presence of interferences and transform them into a close replica of the original signal that is the baseband signal. Therefore the main objective of this thesis is to help one understand the impact of measure and visualize implementation impairments related to both the transmitter and the receiver at all stages of a communication system and how they affect the overall accuracy of the system and its effect on the performance. Towards this end a basic communication system was set up with ability to insert and simulate user selectable levels of multiple implementation impairments and software was created to measure and identify the most common impairments in the design and results are presented through constellation plots, eye diagrams and power spectrum.

A wireless communication system employs a radio frequency (RF) wave to transmit information bearing signals. In modern digital communication systems, sophisticated modulation techniques are developed to modulate information onto an RF carrier waveform, so as to transmit more information. This new book presents signal processing techniques for reducing impairments of analog and RF circuits in wireless communications systems. Engineers, researchers, and students will find full coverage of the topic, including vector modulators, power amplifiers, vector demodulators, group delay distortion in analog/RF filters, digital beamforming networks, and dual polarization systems. Several applications are discussed, including both single carrier and multi-carrier scenarios.
