Abstract
A distortion compensation system includes a first communication node including a first reception unit including an equalizer configured by a first digital filter unit and a first transmission unit including an emphasis circuit configured by a second digital filter unit, and a second communication node including a second transmission unit transmitting a training pattern before receiving normal data from the first communication node. The equalizer converges a filter constant of the first digital filter unit so that an error of the received training pattern is converged. The first transmission unit performs a distortion compensation using the converged filter constant of the first digital filter unit as at least a part of a filter constant of the second digital filter unit of the emphasis circuit, and then transmits the data.
