摘要：
This paper proposes a parallel interference cancellation for multi-carrier DS-CDMA (which is termed FDC-PIC) by integrating frequency diversity combining. The simulations are made over additive white Gaussian noise (AWGN) channel for FDC-PIC with respect to hard, soft and linear decisions, respectively, and we conclude that FDC-PIC acquires a performance superior to match-filtered (MF) receiver, and more interference cancellation stages bring a greater performance improvement. It is also shown that FDC-PIC with soft decision would exhibit the best performance with a high implementation complexity, while FDC-PIC with linear decision acquires performance comparable to that of FDC-PIC with soft decision with a reduced-complexity if the number of the interference cancellation stages is the same, which indicates that FDC-PIC with linear decision has optimal performance/complexity tradeoff and therefore promises for practical application in future.
