摘要
PURPOSE: A feedback interference removing apparatus of an RF(Radio Frequency) relay and a method thereof are provided to estimate an interference signal suitable for the FRF(Fast Rayleigh Fading) characteristic of an inverse direction link through a VSS(Variable Step Size) LMS(Least Mean Square) adaptive algorithm.;CONSTITUTION: A signal processing unit(520) processes a reference signal by using an input signal of an RF relay and an LMS mode. The input signal of the RF relay includes a feedback interferential signal. An error detection unit(530) detects the size of an LMS output error of a signal. A variable step changing unit(540) changes the location of a filter.;COPYRIGHT KIPO 2012
