IEEE 802.16e, mobile Wi-Max, is a wireless technology used to provide very high data rate over large areas to a large number of users where broadband is unavailable. In mobile wireless environment the channel is hostile and behaves adversely. To combat the fading caused by wireless channel IEEE 802.16e uses OFDMA (orthogonal frequency division multiple access) as a transmission scheme based on multicarrier...
Channel estimation in smart antennas for wireless and mobile applications is needed for equalization so as to reduce the ill effects of inter symbol interference (ISI). In our earlier work, it was shown that a time dispersive channel, which can be modeled as an FIR channel can be estimated effectively by using active tap detection NLMS algorithm. The channel was, however, assumed to be stationary;...
