INTERFERENCE CANCELLATION REPEATER AND REPEATING METHOD THEREOF

摘要

Disclosed is an interference removing repeater, which can more accurately cancel a feedback signal without a distortion. To this end, the interference removing repeater according to the present invention includes: a receiving unit to receive an analog signal; a first level measuring unit to measure a level of the received signal; a feedback signal removing unit to remove a feedback signal included in the received signal; a second level measuring unit to measure a level of a signal outputted from the feedback signal removing unit; a signal amplifying unit to amplify the outputted signal; a controller to control amplifying strength based on a result obtained by controlling the first level measuring unit and the second level measuring unit; and a transmitting unit to transmit the signal outputted from the signal amplifying unit.
