Abstract
Based on the method of statistics, this paper derived the output mean value and variance of conventional parallel interference cancellation (PIC), partial parallel interference cancellation (P-PIC) and minimum mean-squared error (MV-PIC) detectors for CDMA. The results indicated that the deviations of mean value and variance of the linear decision parameters were reduced by P-PIC compared with PIC. The output mean value was increased and the variance was decreased by choosing suitable partial interference cancellation coefficient for MV-PIC, and its performance of code error is superior to PIC.
