Abstract
The performance of WIMAX (IEEE 802.16e) systems can be improved by using adaptive antennas in the base stations. These systems operate in Rayleigh/Rician fading channels in the 2-6 GHz band for mobile users with velocities up to 125 km/hr. In this paper, adaptive antenna systems are employed in order to find the direction of arrival (DOA) of the signals and to maximize SINR by using beamforming, Capon, MUSIC and ESPRIT algorithms. The paper also presents the effects of modulation, coding, OFDM symbol duration and Doppler shift on the performance of WIMAX systems.
