Abstract: A base station interface module included in a distributed antenna system includes: a separator configured to separate a base station signal input from a base station and output first and second base station signals; a pre-compensator configured to compensate for at least one of an amplitude and a phase of the first base station signal based on a preset compensation value; a first attenuator configured to attenuate the compensated first base station signal and to output the attenuated first base station signal to the distributed antenna system; and a second attenuator configured to attenuate the second base station signal and to terminate the attenuated second base station signal.
