  • A novel simplified Maximum Likelihood (ML) detection algorithm based on noise analysis is proposed for Vertical-Bell Labs Layered Space-Time (V-BLAST) system. This algorithm chooses the signal points near the reference line in a multi-dimension space to form the signal subset,finally selects the proper signal vector in the subset as final estimation of the transmitted signals based on ML algorithm. Theoretical analysis and simulation shows that the proposed algorithm not only guarantees the near optimum error rate performance, but also has lower computational complexity, and solves the noise enhancement problem.
