Interference cancellation repeater using a feedback cancellation window divided into a feedforward / feedback signal search and methods

摘要

Regard to interference cancellation repeater use this with feedback cancellation window division method and the feedback signal search, by doing so to remove only the feedback signal of the feedforward signal other than interference cancellation repeater, of the source signal and the challenges feedforward I to prevent degradation of quality. By moving the feedback cancellation window, repeater for canceling interference due to the feedback signal according to the present invention comprises, RF signal including a feedback signal repeaters between itself and the feedback signal and is received through a receive antenna the feedback signal from the RF signal window setting part from exploring the feedback signal, to divide the (X _tot) feedback cancellation window on the basis of the feedback signals are searched and (40), on the basis of the feedback cancellation window, said received and a (48) feedback signal removing unit for removing the.
