A wireless communication base station system of the present invention includes a wireless key base station, an optical forward base station, and an optical transmitter which connects the wireless key base station and the optical forward base station to each other. An optical signal modulated by a signal component and that modulated by a distortion component are transmitted from the wireless key base station to the optical forward base station. In the optical forward base station, these optical signals are converted to high-frequency electrical signals, and the high-frequency signal consisting of the signal component is amplified. Thereafter, the amplified signal is combined with the high-frequency signal consisting of the distortion component with their phases opposite to each other, so that the distortion component include in the amplified signal is removed.
