Theoretical Characterization of Memory Polynomial Models With Gaussian Inputs

We consider distortion of a Gaussian signal by a memory polynomial system and prove a theorem about a linear representation of the output. As an application example, we analyze an OFDM system with a nonlinear high power amplifier at the transmitter.
