摘要
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。
V-BLAST is widely acknowledged as the most promising space division multiplexing technique with high spectrum utilization, which is most applicable for future wideband wiless communication system. In this paper, we focus on the model of VBLAST system and propose an Ordered Successive Interference Cancellation algorithm based on dual-substream detection （DD-OSIC） which combines the OSIC algorithm with the spherical detection. The error propagation is reduced and the whole performace is improved. Based on the MATLAB platform, the DD-OSIC algorithm is simulated and analyzed over Nakagami fading channel, the validity and the pacticality of which are proved.
