TITLE

Optimization of DWT Parameters for Jamming Excision in DSSS Systems

ABSTRACT

Direct Sequence/Spread-Spectrum (DSSS) is a commonly used communication technique for civilian and military applications. DSSS signals are characterized by wide bandwidth and a low power spectral density. Despite DSSS is very robust respect to the jamming, if jamming signals are high with respect to the Process Gain (GP ) some techniques must be introduced for guaranteeing a good link performance. For this reason modern satellites are equipped with an anti-jamming system. In this paper the use of the Discrete Wavelet Transform (DWT) for the jamming detection and excision is analyzed. Experiments are performed considering the commonly used jammers types.
