| Abstract: | The operating range of bit rate is achieved from 100 bit/s up to 2M bit/s, and can be varied continuosly. The digital correatos is used for the Sync detection. Both the Sync strategys and the interferencefree meastires are adopted in the Sync selection and protection. The frame synchronizer has been suited to the all VH formes of the chinese telemetry system. In this paper, the design and the fundamentals are prsented. The special skill is expouded emphatically for a kay link in the designed chain. |
