<p>PURPOSE:To simplify the constitution of surrounding base stations, by taking a frame synchronizing signal of a telemetory signal of a satellite as a reference and performing the compensation of phase independently of the propriety of the reception of the phase compensation signal from a central base station, in performing the phase compensation of a transmission data signal. CONSTITUTION:A satellite SAT, a central base station 1 and a plurality of surrounding base stations 2 form a mobile communication system and a satellite digital signal reception antenna 3 of the stations 1, 2 receives the telemetory signal from the satellite SAT. The telemetory signal received at a receiver 5 of the base station 1 generates a referenc clock from a clock generating circuit 6, the clock is encoded at an encoder 8 and transmitted to a transmitter 4 and the plural base stations 2. The telemetory signal receiver at the receiver of the stations 2 is applied to a phase compensation circuit 7 to compensate the transmission data transmitted from the station and 0 transmit the result from the transmitter 4. Each base station 3 performs phase compensation indipendently of the phase compensation signal from the base station 1 to simplify the constitution of the stations 2.</p> |
