* This work is supported by SXSF Grant #20041044. Abstract In CDMA systems multi-access interference (MAI) is a very important component resulting in poor reception performance, however parallel interference cancellation (PIC) can solve this problem to some extent. But in PIC process error cancellation of interference resulting from error decision at the former stage will influence the veracity of decision at this stage. Considering this we proposed a partial parallel interference cancellation (PPIC) multiuser detector based on Hebb learning rule which cancels interference partly by adjusting interference cancellation factors (ICF). Simulations in both DS-CDMA and MC-CDMA systems show that the proposed Hebb-PPIC detector has strong anti-MAI ability and its performance of bit error rate (BER) is improved on the basis of conventional PIC in both conditions of ideal power control and “near-far” scenario.
