Transmission line parameter estimation apparatus and transmission line parameter estimation method

Abstract

A transmission line parameter estimation apparatus includes: a storage unit configured to stores in advance a non-linear phase rotation amount distribution obtained by using time waveform data acquired from a receiver, of a first transmission line, and a non-linear phase rotation amount of a second transmission line different from the first transmission line; and a controller configured to refer to data in the storage unit, and obtains a non-linear constant of each span of the second transmission line based on a distribution of the non-linear phase rotation amount.
