Abstract

A thorough investigation on the convergence and stability of a recently proposed adaptive synchronous CDMA receiver is presented in this paper. The receiver consists of a decorrelator at the first stage and an adaptive interference canceler at the second stage. By using a steepest descent algorithm to adaptively control the weights, the knowledge of the users' received powers in no longer required. It was shown that the system has good 'near-far' resistance, and can approach optimum performance when the interfering users' SNRs are high. Sufficient conditions for the receiver to achieve convergence are derived, and their properties are analyzed.
