Improved Anti-Jam Performance in an Adaptive Spread Spectrum Communication System.
Abstract
This thesis investigates the anti-jam performance of an adaptive spread spectrum communication's system. The adaptive filter is assumed to be ideal in that it perfectly locates the jamming signal and adapts its bandwidth to exactly filter out the jamming signal. The colored-noise (jammer) and bandlimited white noise are considered to have flat power spectral densities within their respective bandwidths. The spread spectrum technique considered is that of direct sequence modulation. Three criteria are used to evaluate the system: autocorrelation peak degradation, signal-to-noise ratio, and intersymbol interference. The results indicate that an adaptive spread spectrum communication's system is able to provide an increased jam resistant communication system. (Author)
