Abstract

When jamming signal is strong enough, the performance of spread spectrum (SS) communications will decline quickly. According to the independence between the SS signal and the jamming signal in baseband, a novel anti-jamming framework of SS communication with independent component analysis (ICA) is proposed in this paper. This anti-jamming framework utilizes the particular structure of SS communications to reduce the degree of the received mixed signals. Because of the advantage of ICA, no prior knowledge of the jamming signal is needed any more, so the operations such as detection and parameter estimation of the jamming signal can be saved. The proposed anti-jamming framework deals with common jamming signals in a unifying framework, which needs not to switch among several anti-jamming techniques corresponding to different type of the jamming. The validity of the proposed method is proved by numerical simulation results at last.
