The New Detection Technique of Phase-Shift Keyed Signals

Abstract

Abstract-We are to introduce the phase-shift keyed signal detector with a relatively simple construction, the one that provides the high-noise immunity. We are demonstrating that the specified detector can extract the phase-shift keyed signals when the signal-to-noise ratio is much less than its working value in the receiver highway. We have determined the expressions for the false-alarm and missing probabilities if the binary phase-shift keyed signal is detected, and we consider the influence of detector parameters on detection performances. The obtained results are corroborated by statistical simulation. We are also to illustrate that the suggested detector can be practically implemented on the base of both analog and digital devices.

Digital Binary Phase-shift Keyed Signal Detector

“…Thus, the useful component is extracted and the estimate of the interference level is made by rejector filtration, which leads to the decision formed concerning either presence or absence of the input PSK signal. Such processing procedure is used in analog PSK signal detectors [7][8][9].…”

“…In a number of radio engineering applications, it is necessary to detect the binary phase-shift keyed (PSK) radio signals [1][2][3][4][5][6]. Analog PSK signal detectors are described in literature [7][8][9]. Their disadvantages are complexity of implementation of analog frequency multipliers and high-stable narrow-band frequency filters.…”
