Performance analysis of direct sequence spread spectrum communications system employing interference excision

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 paper presents a performance evaluation of those excision techniques via the analytical and computer simulation tools. It is found that the analytical performance tools presented are in match 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.
