摘要：

In this paper, we a propose near maximum-likelihood detection (MLD) scheme for multiple-input multiple-output antenna systems over flat fading channels. The new scheme is based on utilizing an initial estimate of the received symbol and discriminate the reliability of the estimated symbol with RD algorithm. If the reliability of the estimated symbol is low, we make a candidate subset of the upper and lower bounds derived from RD algorithm, and then search for the most reliable symbol. The proposed schemes have proved to significantly reduce computational complexity in simulation.
