APPARATUS AND METHOD OF FEEDBACK CANCELLATION FOR RADIO SIGNAL

摘要

PURPOSE: A feedback signal removing device of a same channel relay device and a method thereof are provided to minimize a spectrum distortion due to a DC pilot signal of a restored signal. CONSTITUTION: A reference signal generating unit(508) receives a signal outputted from an RF transmitting unit. The reference generating unit generates a reference signal in which a DC pilot is removed. A replica generating unit(504) generates an output signal of a subtracting unit and a filter factor by using the relationship of a signal generated in a reference signal generating unit. The replica generating unit generates a replica of a feedback signal by using the generating filter factor and a downlink converted signal in a second RF receiving unit.
