Abstract :
In this paper, we propose a spatial multiplexing and diversity joint transmit structure for MIMO-OFDM system where space-frequency block coding (SFBC) is used over all spatial multiplexing layers to obtain both space diversity and frequency diversity gain. We have derived a Monte Carlo probabilistic data association (PDA) detector to get a better bit error rate (BER) performance compared to generic PDA detector. Computer simulation results show that the proposed detector can reduce the intersymbol interference (ISI) greatly, and improve the system performance significantly while the computation complexity has been lower to a proper lever.
