Abstract
Provided are an on-channel repeater for repeating an output signal the same as an input signal on channel by removing feedback signals caused by low isolation of a transmission/reception antenna by converting a transmitted Radio Frequency (RF) signal into a signal of a predetermined band and subtracting a replica of the feedback signal from the converted signal, and by compensating for channel distortion of a reception signal by estimating an inverse of reception channel from a signal acquired by removing the feedback signal, and an on-channel repeating method.
