In this paper, we describe a wireless communication architecture known as optimal detection ordering zero-forcing V-BLAST with maximum a posteriori probability Orthogonal Frequency Division Multiplexing (ZF V-BLAST MAP OFDM) over Monte-Carlo time-variant channels. We simulate ZF V-BLAST MAP OFDM over Monte-Carlo time-variant channel model in the delay spread of 200ns. The symbol error rate performances of ZF V-BLAST MAP OFDM are analyzed and compared with conventional Multiple-Input Multiple-Output (MIMO-OFDM) without ZF V-BLAST MAP decoder. Simulation results show that the performance of ZF V-BLAST MAP OFDM is higher than conventional MIMO-OFDM with same number of transmitter antennas and receiver antennas.
