Posted By: digitalvampire

Hui Liu and Guoqing Li, OFDM-Based Broadband Wireless Networks : Design and Optimization

ISBN 0471723460 | 251 Pages | November 2005

OFDM-based Broadband Wireless Networks covers the latest technological advances in digital broadcasting, wireless LAN, and mobile networks to achieve high spectral efficiency, and to meet peak requirements for multimedia traffic. The book emphasizes the OFDM modem, air-interface, medium access-control (MAC), radio link protocols, and radio network planning.
Learn to produce top-speed, efficient wireless connections with OFDM. This publication covers the latest advances in orthogonal frequency division multiplexing (OFDM), the modem of choice for high-profile wireless systems, including DVB-T, WiFi, WiMAX, and Ultra-wideband. The authors explore the technical concepts at the core of broadband air-interface design and implementation, then investigate advanced principles that open the door to significant improvements in network characteristics not realizable under the current wireless infrastructure.

The publication begins with a comprehensive look at OFDM—its history, principles, and applications. Next is a discussion of the various types of enabling techniques for OFDM modems (e.g., carrier offset estimation, channel estimation, and phase noise and I/Q imbalance compensation), followed by an in-depth treatment of MIMO and smart antennas and their integration with OFDM. Coverage includes both current design methodologies as well as those proposed for future generation systems, including WiMAX and WiFi. The last three chapters examine MAC functionalities and present system considerations for OFDMA-based cellular networks. The authors address the problem of radio resource management through multiple access control, cross-layer optimization, and frequency planning. Finally, appendices are provided for IEEE 802.11a/g and IEEE 802.16e, offering readers the latest developments in WiFi and WiMAX standards.

Key features include:

An emphasis on design concepts and algorithms for the air interface of OFDM-based broadband wireless access networks
Protocols that can capture the full potential of OFDM by jointly optimizing link-level and system-level performance metrics
Cutting-edge research results and articles that deal with OFDM modem and OFDMA-based multiple-access schemes
With detailed design examples provided throughout, this is an excellent hands-on tool for design engineers and professionals as well as graduate students in the fields of wireless and mobile communications.
