Abstract. This paper presents the technique of intermodulation noise power evaluation for OFDM signals with complex envelope limit clipping to compensate the nonlinear distortions caused by HPA (high power amplifier).

Key words: nonlinear power amplifier, OFDM signals, AM/AM and AM/PM characteristics, intermodulation noise.
