PURPOSE:To eliminate the need for an additional circuit and an additional function to a central control station by making each base station compare reception quality at a host station with reception quality at present station sequentially and transmitting and relaying a reception signal with higher reception quality. CONSTITUTION:Transmission lines 29-35 extended in one direction between a central control station 21 and base stations 22-28 are built up, after the base stations 22-28 receive and store once a mobile equipment transmission signal, the base station 22 of the youngest number in the station loop sends a reception signal with reception level information added thereto to the transmission line 29, the next base station 23 compares the reception level with the reception level of the present station and relays the signal as it is when the level of the present station is low, and aborts the signal when the level of the present station is higher, adds the reception signal at the present station to the reception level of the present station and sends the result to the transmission line 30. Similarly, the signal is relayed or sent so as to allow the reception signal of the station received at as maximum level to be arrived to the central control station 21. Thus, it is not required to add a special function to the central control station 21. |
