Bit synchronisation based on the sensitivity function

Synchronization is a fundamental problem in digital communication systems. In systems of greatest interest, the clock reference must be derived from the incoming signal. In connection with efficiency considerations, transmitted power is devoted exclusively to data. The primary purpose of the bit synchronizer is to extract the timing information from a noisy digital signal. The present investigation is concerned with a new procedure whose essential feature is applicability without any a priori information about the incoming signal. The method provided for sensitivity function (SF) synchronization is of an adaptive form and involves the joint synchronization and the estimation of a binary interval. The SF bit synchronization procedure is especially applicable in cases where Gaussian noise and jitter are present.
