Patent ID: 8472872

Claim:
An on-channel repeating apparatus for repeating signals received from a main transmitter or another repeating apparatus through an on-channel, the apparatus comprising: an identification signal generating unit that generates identification signals; a feedback signal removing unit that generates a replica of a feedback signal on a basis of a signal received from the main transmitter or another repeating apparatus and an identification signal, and then removes the feedback signal using the generated replica, the feedback signal removing unit including a subtracting unit that subtracts the replica of the feedback signal from signals in a predetermined band that are converted by the receiving unit, and a replica generating unit that generates the replica of the feedback signal on the basis of the signal output from the receiving unit, the signal obtained by the subtracting unit and the identification signal generated by the identification signal generating unit, and feeds back the generated replica to the subtracting unit; a demodulation unit that demodulates the signal delivered from the feedback signal removing unit into a baseband signal; an identification signal inserting unit that inserts the identification signal generated by the identification signal generating unit into the baseband signal; and a transmitting unit that transmits the baseband signal having the identification signal inserted thereinto.
