This work introduces orthogonal frequency-division multiplexing (OFDM)-based systems from a signal processing perspective. The first part of the book presents a concise treatment of some fundamental concepts related to wireless communications and multicarrier systems. The second part surveys recent developments in a variety of critical design issues, including synchronization techniques, channel estimation methods, adaptive resource allocation, and techniques for reducing the peak-to-average power ratio of the transmitted waveform. Unlike many other books on multicarrier transmissions, this work addresses the issues of resource assignment, synchronization, and channel estimation in depth. The book is for graduate students, design engineers in the telecommunications industry, and researchers in academia. Pun is affiliated with Princeton University. The book is distributed in the US by World Scientific. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
