Abstract

Fourth generation (4G) wireless products are expected to be based on worldwide interoperability for microwave access (WiMAX) systems. It is the optimized receiver algorithms that will differentiate competitive products. In this paper, an important receiver algorithm, channel estimation, is studied for mobile WiMAX systems (IEEE 802.16e-2005). Various channel estimation algorithms are studied and compared for initial channel estimation in downlink of IEEE 802.16e-2005. Various methods are analyzed in terms of their computational complexity, mean square error and bit error rate performances under different channel models
