Abstract
Provided is an on-channel repeater capable of removing feedback signals based on pilot partitioning, which can efficiently remove a feedback signal by quickly coping with even a situation in which a feedback channel changes rapidly, by reducing a filter-coefficient update interval, i.e., increasing the number of times of filter-coefficient creation, through pilot partitioning, and a method thereof. The on-channel repeater includes: a receiver for receiving a signal; a subtractor for subtracting a replica of a feedback signal from the signal received in the receiver to remove the feedback signal; a replica creator for creating a filter coefficient using pilot partitioning, creating a replica of the feedback signal using the created filter coefficient, and feeding back the created replica to the subtractor; and a transmitter for transmitting an output signal of the subtractor.
