Abstract
Disclosed herein an interference cancellation repeater and repeating method. The interference cancellation repeater includes a reception unit, an analog-to-digital (AD) converter unit, a digital processing unit, a digital-to-analog (DA) converter unit, and a transmission unit. The reception unit receives an analog signal. The AD converter unit converts the analog signal into a digital signal. The digital processing unit determines whether a feedback signal is present by analyzing the correlation between the digital signal and a previous transmission signal, and performs an operation of cancelling the feedback signal if, as a result of the determination, it is determined that the feedback signal is present. The DA converter unit converts a signal output from the digital processing unit into a transmission analog signal. The transmission unit sends the transmission analog signal.
