Abstract: The present invention relates to an on-channel repeating apparatus and method. An embodiment of the present invention provides an on-channel repeating method including: subtracting a replica of a feedback signal from a signal received from a main transmitter or another repeating apparatus; demodulating and equalizing the signal to remove noise, a multipath signal, and the remaining feedback signal from the signal; inserting identification signal having good correlation properties into the signal; modulating the signal; and transmitting the modulated signal. Another embodiment of the present invention provides an on-channel repeating apparatus including: a unit that converts signals received from a main transmitter or another repeating apparatus into signals in a predetermined band; a unit that generates identification signals having good correlation properties; a unit that generates a replica from the signals in the predetermined band and the identification signal, and then removes a feedback signal; a unit that demodulates a signal from which the feedback signal is removed; a unit that equalizes the demodulated signal to remove noise, a multipath signal, and the remaining feedback signal therefrom; a unit that inserts the identification signal into the equalized signal; and a unit that modulates the signal having the identification signal inserted thereinto and transmits the modulated signal. According to the present invention, the repeating apparatus repeats output signals that have a small time delay and whose distortion is corrected. Therefore, it is possible to improve the utilization of limited frequency sources, and reduce investment in achieving a repeating apparatus.
