Detection of a PSK Signal Transmitted Through a Hard-Limited Channel
Abstract
This paper considers the problem of the detection of a binary phase-modulated carrier which has been transmitted along with noise through a hard-limiting repeater, corrupted by additional noise, and demodulated by cross correlation and sampling at the receiver. Three equivalent expressions are obtained for the error probability of the receiver output. Two of these expressions take the form of an infinite series involving either confluent hypergeometric functions or modified Bessel functions. A third form allows representation of the error probability in terms of Rice's le function. The model for the communication system to be considered in this paper is shown in Fig. 1. A binary phase-shift-keyed (PSK) signal is assumed to get from the transmitter to the receiver via a hard-limiting repeater in the transmission channel. Additive Gaussian noise is introduced on both the uplink (repeater noise) and the downlink (receiver noise).
