The Research on the Jam Blind Separation of Misalignment Signal

Abstract

In view of noncooperative communication occasions, the separation of the single channel misalignment mixed MSK signals was researched. This research is based on derivation of cyclic spectrum. A frequency shift exists in the misalignment signal, and simultaneously, the mixing signals are transmitted on the channel to generate frequency deviation. BSS makes use of both the deviations to separate signals. The expression of overlap percentage is derived. The simulation results show that the frequency shift is utilized to separate misalignment signal, and the cyclic spectrum estimation is more suitable for the parameter estimation in the blind separation of the alignment signal.KeywordsIndependent Component AnalysisFrequency DeviationIndependent Component AnalysisNormalize Mean Square ErrorGenerate Frequency DeviationThese keywords were added by machine and not by the authors.
