Non-linear distortion compensator, method of compensating non-linear distortion, and communication apparatus

摘要

A non-linear distortion compensator includes: a first signal generator (21) configured to generate a signal with a second multivalued level lower than a first multivalued level from an input signal; a non-linear distortion calculator (22) configured to calculate non-linear distortion of the signal with the first multivalued level based on the signal with the second multivalued level generated by the first signal generator (21); and a non-linear compensator (23) configured to compensate the non-linear distortion of the signal with the first multivalued level based on the non-linear distortion calculated by the non-linear distortion calculator (22).
