The Use of Filters in digital Coherent Receivers Operating in a Jamming and Noise Environment.

Abstract

The effectiveness of the use of front-end bandstop filters in coherent digital receivers versus previously derived optimum jammer waveforms is analyzed. The receivers studied are the binary frequency shift key (FSK) and the binary phase shift key (PSK) coherent (correlator) receivers. The filters analyzed for use against an optimum jammer are a single bandstop region ideal filter, and a second order single bandstop region real filter. General expressions in frequency domain form, are derived for the probability of error of coherent receivers with a front-end filter, then applied specifically to the performance of receivers operating in the presence of noise, jamming, and PSK or FSK modulation. Finally these results are presented in graphical form and, additionally, analyzed and interpreted. (Author)
