Abstract :
This paper proposes the analysis of intermodulation distortion in a multicarrier system, using a method which exploits the relationship between measured nonlinear performance and the signal characteristics of the secondand third-order distortion products. This method, based on a power series expansion, is applicable to situations involving many non-harmonically related tones, where harmonic balance analysis becomes impractical.
