NONLINEAR DISTORTION COMPENSATION APPARATUS AND NONLINEAR DISTORTION COMPENSATION METHOD

摘要

PROBLEM TO BE SOLVED: To be able to control compensation of nonlinear distortion simply with a sufficient precision rate.;SOLUTION: A distortion detector 402 is provided at a receiving device 401. The distortion detector 402 detects nonlinear distortion by regenerating of a received signal received by the receiver 106 and transmits information on the detected nonlinear distortion to a transmitter 101 side as a signal D1 for compensation. A distortion compensator 102 is provided at the transmitter 101, and compensates nonlinear distortion possessed by a transmitting circuit, based on the signal D1 for compensation. A closed loop is employed as the control loop for the distortion detector 402 at the receiving device 401 side and the distortion compensator 102 at the transmitter 101 side.;COPYRIGHT: (C)2010,JPO&INPIT
