Error Probabilities of Spread Spectrum Systems in An Ultra Wideband Source (UWBS) Interference.

摘要

This thesis investigates the potential jamming capabilities of an ultra wideband source (UWBS) jammer on the direct sequence (DS) and frequency hopping (FH) spread spectrum systems using the Advanced Communication Link Analysis and Design (ACOLADE) tool. Error probabilities in both the additive white Gaussian noise channel and the Rayleigh fading channel are obtained with and without convolutional coding. Comparison is made to examine whether an UWBS jamming is more effective on the DS or FH systems given the same jammer power. The thesis also presents how several jammer parameters could be varied in order to inflict more harm on the communication systems.
