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

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 article presents a performance evaluation of those excision techniques via the analytical and computer simulation tools. It is found that the analytical performance tools presented match up with the computer simulation results. It is also shown that a previously proposed adaptive time-frequency exciser consistently outperforms the existing interference excision techniques in the literature
