Abstract

The performance of frame synchronized communication systems is governed largely by the design chosen for the receiver. Some systems employ a structure in which the receiver returns directly to the sync phase when a valid marker is encountered while in the loss verify state. These have been greatly studied. In some systems, the return path in the loss verify phase is implemented as a birth-death process. These systems have not received much attention. In this report, a receiver which employs a birth-death like structure in the loss path is investigated. Expressions for the performance parameters are derived and compared with those obtained for direct return systems. It is found that both types of receivers have the same performance at lower error rates and low loss verify number, M. At high error rates and high values of M, however, the birth-death receiver outperforms the direct-return receiver. To the knowledge of the author, this is the first time that performance expressions have been reported in this form.
