Activity detection of a PSK in unknown white gaussian noise: optimal and suboptimal invariant detectors

Abstract

We propose three solutions for the detection of the activity of phase shift keying (PSK) signals in additive white Gaussian noise environment. The symbol sequence, the complex amplitude of the signal and the noise variance are assumed to be unknown. We show that the uniformly most powerful invariant (UMPI) test does exist only if the signal-to-noise ratio… (More)
