DIGITAL ADAPTATION INTERFERENCE CANCELLATION REPEATER

摘要

A digital adaptation interference cancellation relay capable of controlling renewal performance according to a channel environment is provided to prevent the deterioration of the signal qualification or the speed of an ICS algorithm by controlling the renewal performance according to the channel environment. A variable step size offering part(10) provides step size according to the property of the received signal. An error signal(epsi) removes the interference inference signal from the received signal. A reference signal(rN) delays the error signal. A filter factor output unit(20) produces a next filter factor(Wn) by using previous filter factor(Wn-1).
