RF Analog Impairments Modeling for Communication Systems Simulation. Application to OFDM-Based Transceivers

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.

Radio Receiver Theory

This book is a general course on radio receivers as taught in the Soviet Union to all students majoring in radio communications and broadcasting. Those who plan to specialize in radio engineering take an additional course concerned with radio receiver design and operation and based on the present course. For this reason, this book is primarily concerned with the principles underlying radio reception and radio receiver theory and, does not go into circuit and component details.
