Volterra series based signal processing on integrated communication systems

In this paper, we present a novel behavior frequency domain modeling in application to modern communication systems to describe the third order inter-modulation distortions and harmonic distortions in high frequency signal processing environments based on Volterra series. By using model order reduction techniques, we are able to speed up the simulation time. Two basic model structures including a frequency shaping block and a resistive nonlinear gain block are analyzed. A compositional model based on the proposed two basic models is presented. Different cascade strategy is also discussed. The proposed compositional model achieves simulation results within 6% error on average in comparison with the results from Spectre simulator.
