Abstract: Provided are an on-channel repeater and a method thereof. The repeater receives signals on one channel and distributes the signals on the same channel by converting RF signals from a main transmitter into baseband signals; equalizing them in a high-performance equalizer; adding a repeater identifier to them; modulating the baseband signals with the repeater identifier into RF signals. The repeater includes: a receiver for receiving RF signals; a demodulator for demodulating the RF signals into baseband signals ; an equalizer for equalizing the baseband signals; an adder for adding a repeater identifier to the baseband signals; a modulator for modulating the baseband signals with the repeater identifier added in the adder into RF signals; and a transmitter for transmitting the RF signals modulated in the modulator. The technology of the present invention is used to form an on- channel repeating network in an arbitrary transmission system including a digital television broadcasting system.
