TRANSMITTER

摘要

A nonlinear distortion compensator which can compensate for the nonlinear distortion occurring in the amplifier of a transmission system without using a storage table and has a large distortion reduction effect, by computing nonlinear distortion compensation data by an approximation formula with a compensation coefficient computing unit using the amplitude value of DC-AC base band signals for transmission obtained with a power computing unit, and performing the nonlinear distortion compensation with a nonlinear distortion compensating unit, using the data.
