RF Analog Impairments Modeling for Communication Systems Simulation: Application to Ofdm-Based Transceivers

With the growing complexity of personal mobile communicationsystems demanding higher data-rates and high levels of integrationusing low-cost CMOS technology, overall system performance hasbecome more sensitive to RF analog front-end impairments. Designingintegrated transceivers requires a thorough understanding of thewhole transceiver chain including RF analog front-end and digitalbaseband. Communication system engineers have to include RF analogimperfections in their simulation benches in order to study andquantify their impact on the system performance.

Here the author explores key RF analog impairments in atransceiver and demonstrates how to model their impact from acommunication system design view-point. He discusses the designaspects of the front end of transceivers (both receivers andtransmitters) and provides the reader with a way to optimize acomplex mixed-signal platform by taking into account thecharacteristics of the RF/analog front-end.

Key features of this book include:

• Practical examples illustrated by system simulation resultsbased on WiFi and mobile WiMAX OFDM transceivers
• An overview of the digital estimation and compensation of theRF analog impairments such as power amplifier distortion, quadrature imbalance, and carrier and sampling frequencyoffsets
• An exposition of the challenges involved in the design of bothRF analog circuits and DSP communication circuits in deep submicronCMOS technology
• MATLAB(R) codes for RF analog impairments models hosted on the companion website

Uniquely the book bridges the gap between RFIC designspecification needs and communication systems simulation, offeringreaders RF analog impairments modeling knowledge and acomprehensive approach to unifying theory and practice in systemmodelling. It is of great value to communication systems and DSPengineers and graduate students who design communication processingengines, RF/analog systems and IC design engineers involved in thedesign of communication platforms.
