Semi-autonomous synchronization for TDMA-TDD communication systems

This paper proposes a semi-autonomous frame synchronization scheme for a TDMA (time division multiple access)-TDD (time division duplexing) personal communication system to realize accurate frame synchronization in a simple manner. The proposed scheme selects specific adjacent base stations by the station indicator (SID), carries out high resolution frame phase control, and compensates propagation delay between base stations by using geographical data. This autonomously synchronizes all base stations to each other. Computer simulation results confirm the accurate and stable TDMA frame synchronization of all base stations under the fading environments.<<ETX>>
