Abstract:
There is provided a repeating system for cancellation of a feedback interference signal, including: a PA (Power Amplifier) for power-amplifying an output signal; a feedback ICS (Interference Cancellation System) for canceling a feedback interference signal and detecting a residual error; a pre-distorter for compensating for an error of the PA by applying pre-distortion and compensating for the residual error by using information on the residual error detected by the feedback ICS to linearize the characteristic of the PA; and a control unit for controlling the feedback ICS and the pre-distorter.
