The influence of quantizing and sampling on the signal-to-noise ratio of a complex correlator

Abstract

The combined effects of sampling and phase-quantizing of phase- modulated signals in Gaussian noise are studied and expressed in terms of the output signal-to-noise ratio of a matched filter correlator. The obtained results are the basis for finding the sampling and quantizing losses in other types of correlators or filters. Since only the signal bandwidth, and not the carrier frequency, is considered to be of importance, complex envelopes are used to describe the signals, leading to complex correlator types. The results are summarized in three-dimensional graphs.
