Performance of Coherent Multilevel Digital Communications Receivers in the Presence of Noise and Jamming.
Abstract
The effect of jamming waveforms on optimum multilevel digital coherent communications receivers designed to operate in a Gaussian noise only environment is analyzed and evaluated in terms of receiver performance. Near optimum jamming wave-forms (such as a tone jammer and a weighted sum of signals jammer) are postulated in order to determine their effect on the performance of an M-ary Phase Shift Keying coherent receiver. Additionally, the optimum power constrained jamming waveform is derived and analyzed for an M-ary Amplitude Shift Keying coherent receiver. Graphical results of numerical analyses resulting from the evaluation of receiver performance are presented and interpreted in order to quantify the effectiveness of the jammers. Receiver Performance is measured in terms of word error probability as a function of signal-to-noise ratio. Keywords include: Effect of jamming waveforms on performance of optimum multilevel digital coherent communications receivers..
