%X In this paper, a multiuser detection algorithm (named MMSE-EOPPIC) combined MMSE frequency domain equalization (MMSE-FDE) with Partial Parallel Interference Cancellation based on Energy-Ordering (EOPPIC) is proposed for DS-CDMA system over frequency-selective channels. MMSE-FDE based on overlap-cut method instead of Rake receiver is firstly used to initially estimate all users’ data information, and then partial interference cancellation is in turn implemented for each user in descending order of estimated energy at each iterative stage. In order to improve the detection reliability of each iterative stage, the stronger users’ current stage hard decisions are used to regenerate the weaker users’ multiple access interference (MAI). Simulation results show that MMSE-EOPPIC can efficiently improve the Bit Error Rate (BER) performance of system.
