Adaptive differential interference cancellation multiuser detection method for DS-CDMA communications

The multiuser detection is a signal processing technique which enhances the performance and capacity in DS-CDMA technology. Since its complexity issue was too expensive to handle. there was focus on the suboptimal detectors. In this paper we propose a hybrid method called adaptive differential interference cancellation method (ADIC) which is a hybrid of the differential interference cancellation method and which is then combined in a adaptive way to determine a weight matrix which mill map the outcome of the differential interference cancellation method to come out with a better performance. This paper also looks into the computational cost of different methods using the floating point operation (flops) which is a good estimation of the comparative computational cost if not the exact one.
