Abstract
Provided are an on-channel repeater and an on-channel repeating method. The on-channel repeater includes: a receiving means for receiving a Radio Frequency (RF) signal; a subtracting means for subtracting a replica of feedback signals from the signal received by the receiving means; a replica generating means for calculating the replica based on the signal acquired from the subtraction in the subtracting means and feeding back the replica to the subtracting means; an inverse channel estimating means for estimating inverse of a reception channel based on the signal acquired from the subtraction in the subtracting means and generating filter tab coefficients; a first adaptive filtering means for compensating for channel distortion of the signal subtracted by the subtracting means based on the filter tab coefficients generated in the inverse channel estimating means; and a transmitting means for converting a signal whose channel distortion is compensated by the first adaptive filtering means into an RF signal and performing radio transmission.
