Equalization of BFWA Channels: Theory and Analysis

Broadband Fixed Wireless Access (BFWA) is quickly emerging as a strong network access alternative for the delivery of voice, data, Internet, video and multimedia type applications to business and residential customers. However,the physical limitations of the wireless channel present a fundamental technical challenge to system capacity and reliable communications. Previous studies have shown that BFWA channels are dispersive, they introduce intersymbol interference (ISI) to the transmitted signals, which greatly deteriorates the system performance. An equalization algorithm based on the algebra matrix is introduced and theoretically analyzed in this paper. The results show that this algorithm exhibits a good potential to combat ISI under certain conditions, which suggests the solutions for the future BFWA systems
