An improved parallel interference cancellation (PIC) detector based on conditional likelihood function is presented. The improved PIC benefits from an additional correcting module after the last stage, where the maximum likelihood algorithm using only the conditional likelihood function, which is calculated from the information of the tentative decisions, is employed. Analysis and simulation show that the new algorithm can improve the bit error rate (BER) performance of PIC with much lower
