A performance analysis of interference excision techniques in direct sequence spread spectrum communications

Abstract

It is well known that a proper interference exciser enhances the performance of a spread spectrum communications system. There have been several competing excision techniques reported in the literature. This correspondence presents a performance evaluation of those excision techniques via the analytical and computer simulation tools. It is found that the analytical performance tools presented in this correspondence match up with the computer simulation results. It is also shown that a recently proposed adaptive time-frequency exciser consistently outperforms the existing interference excision techniques in the literature. © 1998 IEEE.
