A synchronizing burst transmission phase control system is provided for a SDMA/SS-TDMA system. The synchronizing burst transmission control system is constituted by a transmission timing error difference measuring means including sync window forming means for limiting a TDMA frame, a comparator comparing measured symbol length with a predetermined reference symbol length for determining a transmission timing error; control means for controlling a transmission timing of a synchronizing burst signal; and switching means for switching a symbol length of a supervisory metric pattern in accordance with the synchronous state of the synchronizing burst signal. |
