Proposal of Framing System Realization for Synchronization Stability Improvement

The purpose of this paper is to propose a simple firmware realization of PCM framing system, which exploits LSI memories for performance improvement and hardware simplification. The proposed system simply consists of a tapped delay line for simultaneous observation of in framing-bits and ROM programmed sequence controller for framing process. Perpormance analyses are made in terms of misframe interval, sync-loss-detection time and reframe time. The proposed strategy proved to be significantly better in reframe time, stability and hardware implementation.
