Equalization and Decoding Algorithms in Broadband Fixed Wireless Access

Broadband Fixed Wireless Access (BFWA) has attracted considerable attention as a promising approach for the next generation high quality and high speed wireless access in frastructure. However, previous studies have shown that BFWA channels are dispersive, they introduce intersym bol interference (ISI) to the transmitted signals, which greatly deteriorates the system performance. In this pa per, we show that the effect of ISI can be greatly alleviated by proper equalization and decoding design, the system performance and capacity can be significantly improved compared to the conventional equalization and decoding scheme
