Abstract
According to one embodiment, a communication repeater system includes a master station device and radio frequency units. The radio frequency unite each convert a signal from each of base station system into an optical digital signal for transmission to the master station device. The base station systems establish communication by time division duplex scheme. The communication repeater system repeats communication between a mobile communication terminal device and each base station system via a corresponding one of slave station devices, and includes a detector that detects each of transmission/reception switching timings between the master station device and each of the radio frequency units, a setter that sets, as reference transmission/reception switching timing, a latest one of the transmission/reception switching timings of the radio frequency unit as candidates of reference transmission/reception switching timing, and a corrector that corrects variation in the transmission/reception switching timings according to the reference transmission/reception switching timing.
