Abstract

This paper explores a new parallel interference cancellation (PIC) scheme for multi-carrier DS-CDMA. For the PIC scheme, frequency diversity technique and the linearization of soft decision function are used to simplify the complexity and improve the system performance. The theoretical analysis over the proposed PIC scheme is detailed, numerical simulations are performed, and main conclusions are drawn as: (1) for the proposed PIC scheme,whether over Rayleigh fading channel or over additive white Gaussian moise (AWGN) channel, more interference cancellation (IC) stages can bring larger performance gain, but with the further increase in the number of IC stages, the performance improves less dominantly; (2) in case of the same IC stages, for the proposed PIC scheme, the linearization of soft decision function will bring the reduction of computation complexity with an ignorable performance loss.
