A Configurable Symbol Synchronizer for Digital Systems

Free registration required

Executive Summary

This paper provides a comprehensive symbol synchronization architecture for deployment in configurable digital receivers. While this is a well researched topic for static symbol rate conditions, significant work remains to be done in determining how to best implement variable data rates and training sequences while maintaining functionality. The synchronizer architecture is a modified version of the basic analog architecture for DSSS synchronizers making it applicable to both wideband and narrowband signals. A known training sequence is received and synchronized to within a half chip accuracy by delaying the generated sequence by half of a chip every sequence period and comparing the correlation to a set threshold.
