Abstract
Provided are an on-channel repeater and a method thereof. The on-channel repeater can extract reception channel information from signals transmitted from a main transmitter or another repeater, compensate for channel distortion caused on a transmission channel by inversely reflecting the extracted reception channel information to the received signals, and transmit the channel-distortion compensated signals through the same channel as a reception channel, and a method thereof. The on-channel repeater includes: a receiver for receiving RF signals transmitted from outside; a down-converter for down-converting the received RF signals into signals of a desired band; a channel-estimator for estimating an inverse value of a reception channel based on the down-converted signals; an adaptation filter for compensating for channel distortion by using a filter having the inverse value of the estimated reception channel; an up-converter for up-converting the channel distortion-compensated signals into RF signals; and a transmitter for transmitting the up-converted RF signals.
