Abstract

We develop an interference suppression scheme for wideband jamming interference in direct sequence spread spectrum communication systems. We consider interference with time-varying spectral components that can be spread both in time and frequency. Our methodology uses the matched signal transform that is highly localized for signals with nonlinear phase along their frequency-modulation (FM) rate. We compare this method with the use of the more computationally intensive quadratic time-frequency representations whose performance is reduced when the interference is multicomponent.
