On WiMAX Performance with Multiple Antenna Transmission

In this paper we aim to investigate the performance of employing several transmit and receive antennas in WiMAX in order to improve the system performance. WiMAX is a wireless technology that provides broadband data at rates over 3 bits/second/Hz. In this paper we will consider multiple antenna techniques that do not require channel knowledge, i.e space-time block coding (STBC), receiver diversity and cyclic delay diversity. The performance results show that STBC and cyclic delay diversity is superior but to an expense in complexity.
