Abstract

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.
