Abstract: Vertical Bell-laboratories Space-Time (V-BLAST) is a multiple transmit and multiple receiving antennas (MIMO) wireless systems.V-BLAST attains very high spectral efficiency while maintains low implementation complexity.Among the detection algorithms of V-BLAST maximum likelihood (ML) detection scheme performs the best;however,its complexity is excessively high.An efficient ML detection algorithm is proposed in this paper.According to simulation results,the proposed scheme has better bit error rate (BER) performance with significant reduction in the computational complexity.

Key words: V-BLAST;maximum likelihood (ML) detection, MIMO system
