The minimum-mean-square-error (MMSE) detection is advantageous in its low-complexity while suffering from severe performance degradation. The post-processing signal-to-interference-and-noise ratio (SINR) distribution of MMSE detector, however, shows the potential of high reliability in the high-SINR detected symbols. We propose a low-complexity multiple-input multiple-output (MIMO) detection scheme...
Linear detectors such as zero-forcing (ZF) and minimum mean square error (MMSE) require only a small fraction of computational complexity compared to maximum likelihood (ML) detector. However, linear detections suffer from severe performance degradation. In this paper, we propose a novel detection scheme which obtains the initial symbol detection by MMSE detector and then perform symbol ordering by...
