Document Type and Number:
Japanese Patent JPH0799815
Kind Code:
B2
Abstract:
PURPOSE:To make a terminal station to always be subordinate to a nearby repeater station whose reception level is the highest by sequentially comparing the reception levels of transmission synchronizing signals from the respective repeater stations for respective ultra-frames, storing maximum transmission timing and permitting the terminal station to be subordinate only to the synchronizing signal of transmission timing stored in a previous ultra-frame at a subsequent ultra-frame. CONSTITUTION:A comparison circuit 15 compares the reception levels of the synchronizing signals transmitted from the respective repeater stations for the respective ultra-frames and maximum transmission timing is stored in a storage circuit 13 in the terminal station. The station is subordinate only to the synchronizing signal of transmission timing stored in the previous ultra-frame at the subsequent ultra-frame. A timing control circuit 4 stores maximum reception level frame information 12, and outputs a reset signal to a time base 5 when an UW detection signal 3 is matched with a maximum reception level frame information 12. The time base 5 is subordinate to a reset signal 18. Such an operation is repeated for the respective ultra-frames.
