Summary: | Based on the structure of perfect space-time block codes(STBC),an equivalent vertical Bell Laboratories layered space-time(V-BLAST) decoding model was given.Minimum mean-square error decision feedback equalizer(MMSE-DFE) was used to preprocess this model and a decoder with boundary controlled Fano tree search algorithm was proposed.This decoder achieves almost maximum likelihood(ML) decoding performance and applies for any antenna configurations.For a wide range of signal-to-noise ratio(SNR),the decoder has lower computational complexity than that of previously proposed near-ML decoders.Operating in complex number field,the decoder is robust for any constellations.The decoder can apply for any multi-input multi-output(MIMO) systems that can be transformed into an equivalent V-BLAST model.Simulation results demonstrate the excellent performance of the proposed decoder. |
