Wireless OFDM Systems

Orthogonal Frequency Division Multiplexing (OFDM) has become the technology of choice for broadband communication in a wireless multipath environment. For instance, it will be used in next generation wireless local area networks (WLANs) and broadband fixed wireless access networks. Although the theory of OFDM is well developed, implementation aspects of OFDM systems remain a challenge. Wireless OFDM Systems brings together the broad and extensive experience of the editor and contributors by providing a comprehensive overview of OFDM implementation issues and OFDM based WLAN systems. The book starts with a discussion of indoor propagation channels, followed by an overview of the basics of OFDM, HIPERLAN/2 and IEEE 802.11a standards. Next, readers are lead through a complete design cycle of an OFDM transceiver, starting with channel estimation and synchronization functionality, and carried through to actual realizations. The different influences of the radio front-end on OFDM communication performance are detailed in the next chapters as well as many OFDM practical problems related to non-linear power amplifiers. The authors conclude with illustrations of several practical implementations involving wireless OFDM transceivers. Wireless OFDM Systems is a must have reference work for wireless communication designers who are building wireless OFDM transceivers.
