PURPOSE:To allow subordinate stations to commonly use a master station carrier equipment and to manage with only one master station carrier equipment, by controlling the frame synchronizing signal of the carrier equipment of each subordinate station on the basis of a frame synchronizing signal in a radio section. CONSTITUTION:On the basis of synchronizing bits from a master station P, the synchronizing pulse generation parts of the carrier terminal equipments 11, 11', and 11'' of subordinatestations C1-C3 are cleared forcibly by using a reset signal to perform frame synchronization in such a way that timing assigned to each station is obtained. Once receiving the synchronizing bits, the equipment 11, 11', and 11'' transmit their assinged parts immediately. They are received by the master station P and a signal array supplied to a carrier terminal equipment 10 is received accurately because it is timed with the frame synchronizing signal of the equipment 10. Consequently, signals of the subordinate stations C1-C3 are received by one equipment 10, thereby constituting a small-sized, inexpensive time-division multiplex multidirectional radio device. |
