Although the effects of a hard-limiting repeater on coherent phase shift keying (CPSK) data transmission systems have been studied, corresponding effects pertaining to differential phase shift keying (DPSK) systems are yet to be examined. The present paper contains the results of a study on DPSK data detection performance when a hard-limiting repeater is part of the overall data link under consideration, and white Gaussian noise is introduced at the repeater and receiver front ends; the extension to the multi-link system, containing cascaded hard-limiting repeaters, is also included. The results obtained were found to be analogous to those of previous CPSK studies. Specifically, the inclusion of the hard-limiter was generally shown to improve probability of error performance when downlink noise is present. A comparison of present results with those of previous ones for corresponding CPSK systems shows that DPSK is degraded noticeably more by downlink noise than its CPSK counterpart.read more

TL;DR: Using the results, it is shown that the error rate does not depend on the noise correlation so long as the a priori symbol probabilities are equal, thereby solving an "open problem" posed by Lee, French, and Hong.

On M-ary DPSK Transmission Over Terrestrial and Satellite Channels
TL;DR: The error rate performance of M -ary DPSK systems is investigated in the presence of phase change offset, noise correlation, and power imbalance, and it is found that the M-ary case is less sensitive to imbalance than is the binary case, and the satellite link performance depends strongly upon the quality of the uplink.

Correction to 'Error Performance of Differentially Coherent Detection of Binary DPSK Data Transmission on the Hard-Limiting satellite Channel'
TL;DR: The error performance of differentially coherent detection of a binary differential phase-shift keying (DPSK) system operating over a hard-limiting satellite channel is derived and shows that as long as the symbols are equiprobable, the error probability is not dependent upon the downlink noise correlation.
