중계기 간섭제거 유닛의 설계 및 구현

A wireless repeater has a problem that the output of the transmit antenna is partially fed back to the receive antenna, which results in feedback interference. In this paper, we introduce a new varable step-size NLMS algorithm, which utilizes correlation between reference and error signals to adjust the step sizes, for cancelling the feedback interference signals, and we make interference cancellation unit using VSS-NLMS algorithm on repeater.
