An Analysis of Coherent and Differentially Coherent Digital Receivers in the Presence of Colored Noise Interference

Abstract

Optimum receivers for detecting digital signals in additive white Gaussian noise are analyzed when operating in the presence of both white noise and colored noise interference. Modulation schemes, such as coherent M-ary Phase Shift Keying (MPSK), Minimum Shift Keying (MSK), Differentially Coherent Phase Shift Keying (DPSK), M-ary Quadrature Amplitude Modulation (MQAM) and 16-state AM/PM are analyzed. Optimum power constrained colored noise interference spectra are developed for each modulation technique analyzed so as to maximize the receiver error probability. Receiver performance, quantified by bit and symbol error probabilities is numerically evaluated and graphically displayed as a function of signal-to-noise ratio and interference-to-signal ratio to demonstrate the effectiveness of this interference in terms of the receiver performance degradation.
