Abstract
Recent research shows that multiple antenna at both transmitter and receiver offers higher data rates compared to single antenna system. The information-theoretical capacity of MIMO grows linearly with the smaller of transmit and receive antenna in rich scattering environment with sufficient high SNR. In this paper, V-BLAST and maximum a-posteriori (MAP) is used improve the performance of the MIMO system. The original V-BLAST algorithm is a multi-layer symbol detection scheme, which detects symbols transmitted at different transmit antennas successively in a certain dataindependent order. The proposed V-BLAST-MAP algorithm differs from V-BLAST only in the ordering strategy of the symbols detected. The complexity of the V-BLAST-MAP is higher than that of V-BLAST. The performance improvement is also significant. In this paper, MATLAB Based simulation result are discussed
