Abstract :
In this paper, we provide the simulation results for the bit error rate (BER) performance of multi-input multi-output (MIMO) systems supporting a 96 Mbps data-rate, based on an IEEE 802.11a OFDM PHY layer under various channel models. A spatial multiplexing system combined with space-time trellis coding (SM-STTC) undergoes the most significant performance degradation in correlated channel environments compared to that in an uncorrelated channel. A spatial multiplexing system combined with space-time block coding (SM-STBC) and a hybrid SM-STBC system produce similar results in correlated fading channels. The V-BLAST system achieves comparable performance to other systems under correlated channels when receive diversity is exploited.
