- In a signal monitoring apparatus of a base station of a communication system having multiple antennas, a transmitting/receiving unit transmits a plurality of transmit signals by using the multiple antennas or processes a plurality of receive signals received through the multiple antennas. A radio frequency calibration unit calibrates the transmit signals transmitted through the multiple antennas, and processes at least one target transmit signal among the plurality of transmit signals so as to monitor the at least one target transmit signal. A signal monitoring unit receives at least one first signal or at least one second signal, and transmits the at least one first signal or the at least one second signal to user equipment. The at least one first signal is a signal processed from at least one target receive signal among the plurality of receive signals, and the at least one second signal is a signal processed from the at least one target transmit signal by controlling the radio frequency calibration unit.
