| Abstract: | 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. |
