摘要

本文提出了一种MIMO系统中采用前向和后向倒易晶格约简(LR)的MMSE检测器。在8×8 MIMO系统中，互反LR辅助检测(LRAD)在BER=10−5时比使用传统LLL算法的LRAD获得了约3dB的BER性能。该方法比反向LRAD获得了约1dB的误码率性能。

MMSE detector using forward and backward reciprocal-lattice reduction in MIMO systems

This paper proposes an MMSE detector using forward and backward reciprocal lattice reduction (LR) in MIMO systems. In the 8×8 MIMO systems, the reciprocal LR aided detection (LRAD) achieves better BER performances about 3dB than the LRAD using the conventional LLL algorithm over BER=10−5. The proposed method furthermore achieves better BER performances about 1dB than the reciprocal LRAD.
