Zusammenfassung:	A wireless interference cancellation repeater and a repeating method thereof are provided to adjust the number of taps and a tap update ratio of a filter for channel estimation according to a change of an external condition. A monitoring and controlling unit(303) monitors a change of an external condition based on an input signal and analyzes an RF channel condition to adjust the number of taps for a filter for channel estimation. An interference signal cancellation unit(304) estimates and generates an interference signal according to the number of taps to cancel an interference signal from the input signal. A DAC(Digital Analog Converter)(305) converts the signal into an RF(Radio Frequency) signal. A transmitting antenna(306) transmits the RF signal.
