Opis

Orthogonal Frequency Division Multiplexing for Wireless Communications is an edited volume with contributions by leading authorities in the subject of OFDM. Its coverage consists of principles, important wireless topics (e.g. Synchronization, channel estimation, etc.) and techniques. Included is information for advancing wireless communication in a multipath environment with an emphasis on implementation of OFDM in base stations. Orthogonal Frequency Division Multiplexing for Wireless Communications provides a comprehensive introduction of the theory and practice of OFDM. Chapter 1, by G. Stuber, briefly introduces the history of OFDM or multicarrier modulation and basic concepts of OFDM, Chapter 2, by Y. (G.) Li, presents design of OFDM systems for wireless communications, various impairments caused by wireless channels, and some other types of OFDM related modulation. Chapter 3 to Chapter 6 address different techniques to mitigate the impairments and to improve the performance of OFDM systems. Chapter 3, by J. Cioffi and L. Hoo, focuses on system optimization techniques, including channel partitioning, loading of parallel channels, and optimization through coding. Chapter 4, by S. Wilson and P. Odling, addresses timing- and frequency-offset estimation in OFDM systems. It also briefly discusses sampling clock offset estimation and correction. Chapter 5, by Y. (G.) Li, deals with pilot aided and decision-directed channel estimation for OFDM systems. Chapter 6, by C. Tellambura and M. Friese, discusses various techniques to reduce the peak-to-average power ratio of OFDM signals. To facilitate the readers, extensive subject indices and references are given at the end of the book. Even though each chapter is written by different experts, symbols and notations in all chapters of the book are consistent."

OFDM (Orthogonal frequency division multiplexing} has been shown to be an effective technique to combat multipath fading in wireless channels. It is being used in various wireless communication systems such as in Digital Audio Broadcasting (DAB) and Video Broadcasting (DVB) in Europe and many of IEEE 802.11 and IEEE 802.16 standards.

This book provides a comprehensive introduction to the theory and practice of OFDM for wireless communications. It includes basic concepts of OFDM, performance optimization, time- and frequency-offset estimation, channel estimation, peak-to-average power ratio reduction, and MIMO OFDM techniques. The key concepts are developed with detailed derivations and proofs to make the material accessible and easy to follow by both students and professionals. While chapters have been written by experts in their respective subject area, the authors have tried to make symbols, notations, presentations and styles consistent. To facilitate readers, the material includes extensive references as well as a large and useful index at the end of the book.

OFDM for Wireless Communications is highly recommended for graduate level courses in advanced digital communication and professional seminars and tutorials on wireless OFDM.
