A Time Synchronization Method Based on Variable-Length Frame

Abstract

If the reference clock is recovered from the input data ,the data rate must at a low speed. Because there is a large clock jitter when the input data at a high speed .In this paper ,a new method of synchronization has carried out for a wireless communication system .The source of data come from the SDI interface,whose rate is 1.485Gbps.The new mechanism avoid introducing the extra hardware by varying the frames structure.The length of frame is changed by adding difference length of 0 at the tail of the frame.
