Abstract
According to an aspect of the inventive concept, there is provided a crest factor reduction (CFR) core, including: a clipper clipping an input signal; a delay unit delaying the input signal; a first subtractor subtracting the clipped input signal from the delayed input signal; an error shaping filter filtering the subtracted signal for shaping an error which occurs by the clipping of the input signal; a digital filter filtering the input signal for cancelling noise of the input signal; and a second subtractor subtracting the filtered subtracted signal from the filtered input signal.
