The performance of the application of the algorithms of multistage parallel complete interference cancellation and multistage parallel partial interference cancellation to CDMA system with timing errors is analyzed. The system signal model is set up, and the relevant formulas are given out. The performance comparison under the effects of near-far is also investigated. It is concluded that the performance of the algorithm for partial interference cancellation is higher than that of complete interference cancellation.
