Low-complexity MIMO Data Detection Using Dual Lattice-Basis Reduction

摘要：

Lattice reduction is an effective technique for improving the performance of MIMO data detection. In this paper, we analyze lattice reduction processing on the basis lattice and the dual lattice for MIMO detection and investigate the parameters which affect the complexity of the LLL algorithm. Through use of the dual lattice in the LLL algorithm, the BER performances are improved about 2.2dB at BER105 for the 88 MIMO systemcompared to the LLL algorithm. We demonstrate the dual lattice as the reduced lattice can diminish the effect of noise with low complexity.
