Partial Decision OSIC:a Modified Detection Algorithm for VBLAST
部分判决的OSIC:一种改进的VBLAST解码算法

Ordered Successive Interference Cancellation (OSIC), the conventional detection algorithm for VBLAST, decreases the complexity, comparing with the Maximum Like lihood (ML), but its performance is much worse than that of ML. In this paper, Partial Decision OSIC (PD_OSIC), a modified detection algorithm is presented for VBLAST. It increases the number of candidate decision symbols and uses ML detection in the last layer, so it improves the detection performance. The simulation results show that the algorithm proposed gets far better performance than OSIC.
