Compensating circuit and compensating method

Abstract

A compensating circuit comprises a matching circuit, for matching an initial signal and a transformed signal to generate a matched signal; a calculating circuit, coupled to the matching circuit, for calculating a function of the matched signal; a phase-rotating circuit, coupled to the calculating circuit, for rotating a phase of the function according to a determined phase to generate a phase-rotated function; a determining circuit, coupled to the phase-rotating circuit, for determining a parameter according to the phase-rotated function; and a mixing circuit, coupled to the determining circuit, for mixing the parameter and the transformed signal to generate a compensated signal.
