Narrowband Jammer Suppression in Spread Spectrum System Using SAW Devices.

摘要

An analysis of a binary spread spectrum PSK communication system operating in the presence of a sine wave jammer will be presented. The receiver will consist of a real time Fourier transformer followed by a filter designed to attenuate the interference. The output of this latter filter is inverse transformed and then put through a matched filter for final detection. The probability of error of this system will be derived and compared to that of a receiver employing just a matched filter (i.e., one that does not attempt any explicit filtering to remove the interferer).
