PURPOSE: A repeating device for removing a feedback interference signal is provided to remove the feedback interference signal properly while keeping an SNR(Signal to Noise Ratio) performance by converting a frequency of the signal from which the feedback interference signal is removed into a high frequency. CONSTITUTION: A receiving antenna(10) receives a signal transmitted through the wireless network. A low frequency converter(20) converts a frequency of the received signal into a low frequency. A feedback interference remover(30) estimates a feedback interference signal in a digital area. The feedback interference remover removes the feedback interference signal in an analog area. A high frequency convert(40) converts the frequency of the signal from which the feedback interference signal is removed into a high frequency.
