Patent ID: 10396851

Abstract:
It is made possible to compensate for a waveform distortion having semi-fixed characteristics and a waveform distortion varying at high speed with a high degree of accuracy.An equalization processing circuit according to an exemplary aspect of the present invention includes frequency domain equalization means for performing a frequency domain equalization on a digital signal using an inputted frequency domain equalization coefficient; time domain equalization means for performing a time domain equalization on a digital signal using an inputted time domain equalization coefficient; waveform distortion detection means for detecting a dynamic waveform distortion and a quasi-static waveform distortion of an equalized digital signal on which the equalization to be performed; frequency domain equalization coefficient control means for calculating a frequency domain equalization coefficient based on a quasi-static waveform distortion; and time domain equalization coefficient control means for calculating a time domain equalization coefficient based on a dynamic waveform distortion.
