PURPOSE:To improve the frame utilizing efficiency by varying number of times of repetition of a synchronization burst in response to line quality of a satellite line in the TDMA communication system in which a base station and a slave station send the same synchronization burst to each other via the satellite line by a prescribed number of times and a majority decision discrimination section implements majority decision under the control of a synchronization control section. CONSTITUTION:A base station 1 has a line quality detection section 8 detecting the quality of a satellite line 3 and setting a prescribed number of times of repetition of a synchronization burst corresponding to the said line quality. Then the base station 1 sets number of times of majority decision for majority decision sections 6,7 to the majority decision sections 6,7 through a synchronization control section 4 of its own station and a synchronization control section 5 of a slave station respectively. Thus, the TDMA frame utilizing efficiency is improved when the line quality is excellent. |
