More Information
Summary:An interference cancellation repeater includes: a first transmission/reception processing unit configured to convert a radio frequency (RF) input signal input via a link antenna communicatively coupled to a base station into a digital input signal; an interference canceller configured to cancel an interference signal from the digital input signal and to output an interference canceled signal; a second transmission/reception processing unit configured to convert the interference canceled signal into an RF output signal and to amplify the RF output signal; and a gain controller configured to detect a gain change of the interference cancellation repeater based on the interference canceled signal and to change a current gain of the interference cancellation repeater to a target gain by adjusting intensity of at least one of the RF input signal, the interference canceled signal, and the RF output signal when the gain change of the interference cancellation repeater is detected.
