摘要：Large-scale multiple-input multiple output is termed to be one of the key technology in future generationmultiple cellular systems supporting the 3GPP LTE. LTE includes MIMO technology with orthogonal frequencydivision-multiple access technology surrounded by the downlink and single carrier-frequency division multiple access(SC-FDMA). This paper introduces a novel low-complexity multiple-input multiple-output (MIMO) detector tailoredfor single-carrier frequency division-multiple access (SC-FDMA) systems, suitable for efficient hardwareimplementations. The proposed detector starts with an initial estimate of the transmitted signal based on a minimummean square error (MMSE) detector. Subsequently, it recognizes less reliable symbols for which more candidates in theconstellation are browsed to improve the initial estimate. An efficient high-throughput VLSI architecture is alsointroduced achieving a superior performance compared to the conventional MMSE detectors. The performance of theproposed design is close to the existing maximum likelihood post-detection processing (ML-PDP) scheme, whileresulting in a significantly lower complexity, i.e., and times fewer Euclidean distance (ED) calculations in the 16-QAMand 64-QAM schemes, respectively.
