Abstract

In this paper, we propose an adaptive multi-user interference cancellation for direct sequence ultra-wideband (DS-UWB) communications. Much of the published research to date has focused primarily to the multi-user detection based on conventional CDMA systems, however, those items have some matters such as slowly convergence rate and complexly computation. The proposed algorithm is a parallel iterative interference cancellation algorithm, and makes use of MMSE optimum filter in each user, at the same time, it takes the other users as the interference. The simulation result shows that it has a faster convergence rate
