Imperfect Differential Detection of a Biphase Modulated Signal - An Experimental Analytical Study

Abstract

The results of an experimental investigation of the effects of bit synchronization error and carrier frequency uncertainty on the performance of receivers used to demodulate differential phase shift keyed (DPSK) signals are presented. Also, previous analytical results relating to the differential detector (DD) are summarized and an expression for the performance of the perfectly timed DD with frequency uncertainty is derived. The bit error probability and the probability of two consecutive errors are used as performance measures. The experimental and analytical results obtained apply to cases in which the carrier is biphase modulated with the differentially encoded bit stream, the (equivalent) noise at the receiver input is white and Gaussian distributed, the bit synchronization error is Gaussian distributed, and the error in the carrier frequency estimate is constant as a function of time.
