  • Abstract
    In this paper we propose a simple improvement for an adaptive baseband predistortion without memory driven with QAM signals. We combine a predistortion technique and Input Back-off term. The computer simulation confirms that for the case of QAM modulation amplified with High Power Amplifier a performormance was improved. The case of 64-QAM transmission over a radio communications link is studied in details.
