description PURPOSE: An interference removing apparatus having a phase compensation circuit is provided to generate a reference(pilot) signal for removing an interference component which occurs in a receiving signal in a wireless communication transmission/reception system, detecting a component of a received signal, compensating a delay time, adjusting a phase and amplitude, generating a signal received based on a reference signal and a signal of the same phase and amplitude and mixing the generated signal with an original signal, and remove an interference. CONSTITUTION: A signal f1 transmitted from a base station(211) is received through an antenna1(212). The component of the received signal is detected by a bidirectional coupler1(213) connected at the next terminal of the antenna1(212) and is transferred to a delay line(214) of the interference removing apparatus(218). The delay line(214) compensates a delay of the signal f1 which is generated between the antenna1(212) in the direction of the base station and the antenna2(222) in the direction of the terminal.
