Summary: 
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 timing control, and compensates the propagation delay between base stations by using geographical data. This autonomously synchronizes all base stations to each other. Computer simulation and analysis results confirm the accurate and stable TDMA frame synchronization of all base stations even in fading environments.
