APPARATUS AND METHOD FOR ON-CHANNEL REPEATING

摘要

An apparatus and a method for relaying the same channel are provided to relay an output signal having short time delay whose distortion is corrected, thereby improving use efficiency of limited frequency resources. An identification signal generating unit(810) generates an identification signal having a good correlation property. A feedback signal removing unit(804) generates a replica of a feedback signal based on the identification signal and a receiving signal from a main transmitter or another relay device. And the feedback signal removing unit removes the feedback signal by using the generated replica. A demodulation unit(806) converts the signal received from the feedback signal removing unit into a baseband signal. An identification signal insertion unit(812) inserts an identification signal generated by an identification signal generating unit into the baseband signal. Transmitting units(816,818) transmit the baseband signal to which the identification signal is inserted.
