Receiving apparatus, method of compensating for waveform degradation of received signal, apparatus and method for detecting waveform degradation, and apparatus and method for measuring waveform

摘要

In a receiving apparatus, there are included a compensation characteristic variable type waveform degradation compensating unit capable of compensating for waveform degradation of a received signal stemming from a transmission line, a received waveform measuring unit for measuring waveform data on the received signal (which will be referred to hereinafter as “received waveform data), and a control unit for controlling a compensation characteristic of the waveform degradation compensating unit to minimize a difference between frequency data on the received signal, obtained by converting the received waveform data acquired by the received waveform measuring unit into a frequency domain, and frequency data on a reference waveform free from waveform degradation. With this configuration, certain compensation for the waveform degradation of the received signal stemming from chromatic dispersion or the like becomes feasible without using a dispersion compensation fiber.
