METHOD FOR SEARCHING FEEDFORWARD/FEEDBACK SIGNAL AND DIVIDING FEEDBACK CANCELLATION WINDOW AND INTERFERENCE CANCELLATION REPEATER USING THE SAME

摘要

A method for searching feedforward/feedback signals and dividing a feedback cancellation window and an oscillation cancellation repeater using the same are provided to remove only the feedback signal except the feedforward signal, thereby preventing quality deterioration of a received signal. A radio signal including a feedback signal(52) and a feedforward signal(53) is received through a link antenna of an oscillation cancellation repeater which removes the feedback signal by using a feedback removal window(61). The feedforward signal is detected. The feedback removal window is reset to remove the feedback signal so that the detected forward signal is not included in the feedback removal window.
