TRANSMITTING DEVICE AND TRANSMITTING METHOD

摘要

A line variation estimating section (101) estimates the variation of the line between a transmitting device (100) and a receiving device (200). A symbol rate determining section (102) determines the symbol rate on the basis of the variation of the line to transmit a signal at an increased symbol rate if the line variation is significantly fast because of fast phasing to make relatively minute the line variation between symbols or in a burst. Thus even if the line variation is significantly fast because of fast phasing, an adaptive equalizer can have a sufficient follow-up performance almost without increasing the device structure, maintaining the favorable communication quality.
