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.
