Abstract Ordered Successive Interference Cancellation (OSIC), the conventional detec-tion 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 in-creases 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.
