Vertical-Bell Labs Layered Space-Time (V-BLAST) detection algorithm comprises forward and reverse ones according to different detection orders. Combining both algorithms, a novel detection algorithm is presented in this paper in view of the characters of adaptive modulation. New algorithm first detects the saturated channel with maximum modulation size, then detects the invalid channel which does not meet the minimum SNR threshold, finally detects the remaining channel as the criteria minimizing distance between post-detection SNR and threshold set. Simulation results show that the spectral efficiencies of proposed algorithm tend to forward or reverse order at high or low SNR respectively, and outperform the both at middle SNR.
