Abstract: According to an aspect of the inventive concept, there is provided an interference cancellation repeater for repeating a long term evolution (LTE) signal between a terminal and a base station, the interference cancellation repeater includes: an interference canceller configured to generate a restored LTE signal by canceling a feedback signal included in an input LTE signal; a sync signal detector configured to detect a first sync level which is a level with respect to a sync signal of the input LTE signal and a second sync level which is a level with respect to a sync signal of the restored LTE signal; and a gain controller configured to control a signal amplifier according to isolation calculated based on a difference between the first sync level and the second sync level.
