Combined LSD and DFE Detection for V-BLAST
一种组合的LSD和DFE V-BLAST检测算法

BLAST can effectively increase information rate in multi-antenna system. The simplest space multiplex method is V-BLAST, which has simple detection algorithm such as ZF-DFE, MMSE-DFE, ML and ML-DFE etc. This paper discussed methods to improve the ML-DFE algorithm, proposed combined LSD and DFE detection algorithm based on ZF and MMSE criteria. Simulation results show that large performance improvement can be obtained when the LSD algorithm output only 3 detection results, and the algorithm based on MMSE criteria has better performance than based on ZF criteria.
