Abstract

IEEE 802.16 is an emerging global broadband wireless access standard capable of delivering multiple megabytes of shared data throughput supporting fixed, portable and mobile operations. WiMAX represents a scalable and cost-effective solution to offer wider area coverage, improved performance in terms of QOS, service continuity in case of terrestrial network failure and long range user mobility. The ever increasing demand of OFDMA and MIMO, plays a major role in multiuser and multicarrier frame work. We propose a suboptimal, subcarrier allocation criteria for OFDMA-MIMO systems. The computational complexity grows linearly with the number of users and the number of sub carriers. Numerical results are presented to compare the two sub carrier allocation criteria with the optimal criterion. It is observed that BER and FER approaches rapidly for lower energy to noise ratio.
