PURPOSE:To avoid a phase difference between plural peripheral base stations with simple circuit constitution by adjusting the phase with loopback of a wired system. CONSTITUTION:A control means 107 sets a half of a phase difference detection signal from an in-incoming bit phase difference detection means 105 to an in- outgoing bit delay adjustment means 102 and an in-incoming bit delay adjustment means 103. Then the control means 107 sets a half of a phase difference detection signal from an inter-incoming bit phase difference detection means 106 to an inter-outgoing bit delay adjustment means 101 and an inter-incoming bit delay adjustment means 104 when the phase difference detection signal from the inter-incoming bit phase difference detection means 106 is an even number. Moreover, after the value of the inter-incoming bit phase difference detection signal is an even number, a half of the detected value is set respectively to incoming/outgoing inter-bit delay adjustment means 101, 104. Thus, the phase of the transmission timing of the data is adjusted so that there is no phase difference among plural peripheral base stations 1301-130m. |
