Issues and Performance Study of Jammer Suppression in Direct Sequence Spread Spectrum Communications using Fast ICA

Abstract

Independent Component Analysis (ICA) technique separates mixed signals blindly without any information of mixing system. The present work studies and analyses the issues involved in interference rejection in direct sequence spread spectrum communication systems based on Independent Component Analysis technique. The ICA technique tries to separate the unwanted interfering signal from the desired signal so that contamination of the desired spread spectrum signal is minimized. The effect of the inherent ambiguities of ICA on this model is also analyzed. Results of the simulation study carried out on the ICA assisted jammer mitigation for spread spectrum communication is presented in this work.
