This paper proposed a detection method combined the list detection with partial successive interference cancellation (SIC) based on the reciprocal lattice-reduction in MIMO system. List detection is an effective detection method for improving the performance of MIMO signal detection, but the computational expense depending on the list length is the bottleneck. To reduce the complexity of the list...
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.
This paper proposes an MMSE detector applying the reciprocal lattice reduction (LR) in MIMO systems. The proposed detector achieves as good as or better BER performances than the LR aided detector using the conventional LLL algorithm and using the Seysen's algorithm in the 4×4 and the 8×8 MIMO systems. It also achieves BER curves to be as steep as or steeper than those using the maximum likelihood...
