Contains eight contributions written by electrical engineers, systems architects, and others from Europe and the US addressing new developments in OFDM-based wireless local area networks (WLANs). Includes a discussion of indoor propagation channels, an overview of the basics of OFDM, HIPERLAN/2, and EIII 802.11a standards. Also covered is the complete design cycle of an OFDM transceiver, starting with channel estimation and synchronization functionality, through to actual realizations. The different influences of the radio front-end on OFDM communication performance are detailed in the next chapter, as well as many OFDM practical problems related to non-linear power amplifiers. In conclusion, the authors provide illustrations of several practical implementations involving wireless OFDM transceivers. Suitable for wireless communication designers building wireless OFDM transceivers.
