Abstract

In this paper, we propose an effective design of successive interference cancellation (SIC) multiuser detector for Direct Sequence CDMA using Constant Modulus Algorithm (CMA). The SIC receivers are simple in structure and robust in combating multiple access interference (MAI) and near far effect. However, two of the main practical issues of SIC are the error propagation and imperfect channel estimation. To overcome these problems, we employ a simple adaptive CMA algorithm within SIC despreader to provide reliable estimate of the desired signal amplitude and for mitigating the effect of fading channel. Modeling and simulation of the proposed detector shows impressive single user bound reaching performance in fading channel with AWGN and robustness in different system loading and near far conditions.
