Abstract: According to one embodiment, a base station apparatus (1) includes: a radio equipment control (2) that generates a baseband signal including data (D1); a microwave apparatus (4) that modulates the baseband signal to a microwave to transmit by radio; a microwave apparatus (5) that demodulates the received first microwave to the baseband signal, then extracts a clock (CLK1) from a cycle of the data (D1) included in the baseband signal, imports the baseband signal in synchronization with the clock (CLK1), and plays back the data (D1); and a radio equipment (3) that modulates the data (D1) played back by the microwave apparatus (5) to a high-frequency signal, and the microwave apparatus (5) outputs dummy data instead of the played back data when a frequency fluctuation amount of the clock (CLK1) exceeds a predetermined range.
