DISTORTION COMPENSATION APPARATUS CAPABLE OF ACCURATELY COMPENSATING THE DISTORTION OF A SIGNAL BY SELECTING AN APPROPRIATE DISTORTION COMPENSATION COEFFICIENT, AN AMPLIFYING APPARATUS, A TRANSMISSION APPARATUS, AND A DISTORTION COMPENSATION METHOD
DISTORTION COMPENSATION APPARATUS CAPABLE OF ACCURATELY COMPENSATING THE DISTORTION OF A SIGNAL BY SELECTING AN APPROPRIATE DISTORTION COMPENSATION COEFFICIENT, AN AMPLIFYING APPARATUS, A TRANSMISSION APPARATUS, AND A DISTORTION COMPENSATION METHOD
PURPOSE: A distortion compensation apparatus, an amplifying apparatus, a transmission apparatus, and a distortion compensation method are provided to perform distortion compensations using a distortion compensation coefficient acquired from a memory part.;CONSTITUTION: A distortion compensation apparatus(110) compensates the distortion of a signal by an amplifier(120). A multiplication part(111) compensates the distortion in an input signal using a distortion compensation coefficient. An LUT (114a) memorizes the distortion compensation coefficient. An address generation part(112) generates a first address in order to get the distortion compensation coefficient from the LUT based on the power of the input signal. The address generation part generates a second address in order to get the distortion compensation coefficient from the LUT based on the amplitude or phase of the input signal or a power value according to the power of the input signal.;COPYRIGHT KIPO 2012
