Fast converging blind adaptive multiuser detector for DS-CDMA system

Abstract

A fast converging blind adaptive multiuser detector is proposed in this paper. In the proposed method, the convergence of the blind adaptive detectors for weak power users is accelerated by successively canceling the interference of the strong power signals from the received signal. The order and channel parameters for the interference cancellation are determined from the steady state of the detectors. Numerical results presented show that satisfactory performance can be achieved in various environments.
