ABSTRACT:
A high-frequency signal output from an active radio transmitter is input to a phase comparator via a standby radio receiver. A transmitting data processing unit delays a frame data signal and a clock signal by a predetermined time and inputs them to the phase comparator. The phase comparator compares the phases of the two frame data signals and the two clock signals, and the delay time adjuster in the active radio transmitter adjusts the phases of the frame data signal and the clock signal input from the data processing unit so that the phases of both data signals and clock signals are coincident with each other. Similarly, the delay time adjuster in the standby radio transmitter adjusts the phases of the data signal and the clock signal input from the data processing unit. In this manner, the delay times (signal phases) of the active radio transmitter and the standby radio transmitter are automatically adjusted during the operation of a radio equipment.
