Abstract

In recent year, the Direct Sequence Spread Spectrum (DSSS) technology has been introduced as an attractive approach to guarantee anti-interference capability in satellite communication system. However, due to the limitation of the DSSS, the system performance has been greatly deteriorated while a strong interference is out of the tolerance of the system. Meanwhile, what the wavelet packet transforms is ideally suitable for the interference detection and suppression of DSSS satellite communication system by exploiting its excellent local time-frequency domain analysis capability. In this paper, a novel algorithm has been put forward to achieving position and interference suppression through combing the sub-band power ratio with minimum power thresholds which are based on the analysis on the optimal wavelet packet decomposition. Simulation result shows that the proposed interference suppression algorithm significantly improves the anti-jamming capability of DSSS satellite communication system compared with the traditional FFT algorithm.
