PSK Error Performance with Gaussian Noise and Interference
A. Rosenbaum · Bell System Technical Journal · 1969
A single, constant amplitude, in-band, additive interference is included in the analysis of detecting phase shift keyed signals in gaussian noise. For coherent detection we give a method applicable to any M-phase system, and evaluate the symbol error probability for M = 2, 3, and 4. For differential detection we treat the important cases M = 2, 4, 8, and 16, offering comprehensive numerical results for each. The analysis in each case is based on a single sinusoid with random phase adding to the noisy phase shift keyed signal. The results are then interpreted to include an angle modulation impressed on the continuous wave interferer. The receiver consists of an ideal phase discriminator with a perfect slicer. The channel is also assumed ideal in that intersymbol interference is not considered.
