MIMO系统中格点减少检测算法研究
Research on detection algorithm with lattice reduction in MIMO systems
摘要
Abstract
Signal detection in receiver will be much more complex because of bad condition of actual communication systems.This letter adopted lattice-reduction-aided schems to the mmse criterion here to enhance the performance of detection in such ystems.The performance could easily reach near-maximum-likelihood detection performance just with complexity of multinonmial, and the complexity of the algorithm would be even lower according to adopting QR decomposition.Results of emulations show that error performance of MIMO systems without coding will be improved through lattice-reduction-aided MMSE-SIC algorithm.关键词
