摘要：
In this paper, a chip level ordered successive spatial and multiuser interference cancellation (OSSMIC) receiver architecture is presented for downlink multiple-input multiple-output multi-carrier code division multiple access (MIMO MC-CDMA) systems. The proposed receiver performs ordered layer space-time detection. Unlike the existing ordered successive interference cancellation (OSIC) receiver, the proposed receiver cancels both spatial & multiuser interference in the SIC process. This allows detection in multiuser scenario, which is not possible in conventional chip level OSIC receiver. Simulation results show that the proposed receiver significantly outperforms both the existing chip level OSIC detector and the chip level linear receiver. As the proposed receiver only requires the knowledge of the desired user's spreading sequence, it is a viable solution for downlink MIMO MC-CDMA communications.
