Abstract

In this paper a near-far resistance detector for asynchronous Code-Division Multiple-Access (CDMA) systems operating in Additive White Gaussian Noise (AWGN) channels is presented. The multi-user interference caused by K users transmitting simultaneously, each with a specific signature sequence, is completely removed at the receiver. The complexity of this detector grows only linearly with the number of users, as compared to the optimum multi-user detector which requires exponential complexity in the number of users. A modified algorithm based on time diversity is described. It performs detection on a bit-by-bit basis and overcomes the complexity of using a sequence detector. The performance of this detector is shown to be superior to that of the conventional receiver.
