PURPOSE:To extend the distance of a transmission line by adjusting a reception timing of an input reception burst by a centralized control station for each burst with a delay so as to prevent collision of received burst signals in the centralized control station with a mobile station or a base station. CONSTITUTION:A timing control section 53 is provided to a centralized control station 50 in the mobile communication system, Then a delay adjustment circuit 501 generates a reception demodulation timing signal (b) in response to a transmission delay time between mobile stations 71-76 or radio base stations 61-63. A demodulator 12, a frequency converter 21 and an SW control circuit 58 execute prescribed operation and processing according to the timing signal (b). Thus, even when each transmission delay time difference between the centralized control station and the mobile station or the radio base station is large, collision of received burst signals in the centralized control station is avoided and the range of the transmission line between the centralized control station and the radio base station is extended. |
