Satellite broadband transmission signals require reduction in signal distortion to maximize transmitter power source efficiency. This paper proposes and investigates the effects of using a Volterra filter to adaptively compensate for nonlinear amplifier distortion and frequency characteristics in satellite communications. The effectiveness of a Volterra filter was verified by computer simulations. The computer simulations indicated that the bit error rate (BER) characteristics for multilevel modulation are significantly improved. We expect an improvement in transmitter power source efficiency of an earth station of a satellite communication system.
