VBLAST系统一种基于双子流检测的定序连续抵消算法

摘要

Focused on the model of VBLAST system, an Ordered Successive Interference Cancellation algorithm based on dual-substream detection ( DD-OSIC ) is proposed which combines the OSIC algorithm with the spherical detection.The error propagation is reduced and the whole performace is improved.Based on the MAT-LAB platform, the DD-OSIC algorithm is simulated and analyzed over Nakagami fading channel, the validity and the pacticality of which are proved.%针对VBLAST系统,提出了一种基于双子流检测的改进定序连续抵消算法(DD-OSIC),并将球形检测与OSIC检测算法相结合,减少误差传播并增强了整体性能.通过MATLAB仿真平台,对算法在Nakagami衰落信道环境下的性能进行了仿真和性能分析,证明了算法的有效性和实用价值.
