Research on detection algorithm with lattice reduction in MIMO systems
MIMO系统中格点减少检测算法研究*

Signal detection in receiver will be much more complex because of bad condition of actual communication systems. This letter adopts lattice-reduction-aided schems to the mmse criterion here. The performance can easily reach near-maximum-likelihood detection performance just with complexity of multinonmial, and the complexity of the algorithm will 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.
