Patent ID: 7123845

Claim:
A receiving apparatus with a waveform degradation compensating function, comprising: first waveform degradation compensating means of a compensation characteristic variable type for compensating for waveform degradation of a received signal; second waveform degradation compensating means of a compensation characteristic variable type for further compensating for waveform degradation of an output of said first waveform degradation compensating means; received waveform measuring means for measuring waveform data on said received signal (which will be referred to hereinafter as “received waveform data”); control means for controlling compensation characteristics of said first and second waveform degradation compensating means so that a difference between frequency data obtained by converting said received waveform data, acquired by said received waveform measuring means, into a frequency domain and frequency data on a reference waveform free from waveform degradation reaches a minimum; and time-constant generating means for making a difference between a speed of the control of said compensation characteristic of said first waveform degradation compensating means by said control means and a speed of the control of said compensation characteristic of said second waveform degradation compensating means by said control means.
