PROBLEM TO BE SOLVED: To obtain an efficient initial connection system for a multi-stage repeating system. SOLUTION: The output of a demodulator 13 is connected to a repeating-tage number separating circuit 18 and repeating-stage number information is separated from a channel for control and outputted to a repeating-stage number+1 circuit 19 and a transmission timing adjusting circuit 28. The circuit 19 adds one to the repeating-stage number information and outputs the resulting information to a multiplexing circuit 14. The multiplexing circuit 14 multiplexes it with repeating-stage number information on the control channel. The output of a demodulator 24 is connected to a burst signal detecting circuit 27 for initial connection, which detects and outputs a position error of a burst signal for initial connection from a slave station to the multiplexing circuit 14. The multiplexing circuit 14 multiplexes it with the control channel. The repeating- stage numer information separated by the separating circuit 18 is inputted to the transmission timing circuit 28, and a burst signal sending-out circuit 29 for initial connection uses it as the timing of initial connection by its station and outputs the burst signal for initial connection. |
