Operating Characteristics for Maximum Likelihood Detection of Signals in Gaussian Noise of Unknown Level. II. Phase-Incoherent Signals of Unknown Level,

摘要

The detection and false alarm probabilities for maximum likelihood detection of nonfluctuating phase-incoherent signals in stationary Gaussian noise,where the received signal and noise levels are unknown,are derived and evaluated. This procedure is carried through for two cases involving different assumptions about the received signals. In the first case,the signal amplitudes in M potential-signal observations are assumed to be different and unknown values for each sample. In the second case,the signal amplitudes,although unknown,are assumed to be the same for all M observations. (Modified author abstract)
