Abstract: A non-iterative frequency domain method for the accurate and efficient simulation of nonlinear systems is presented. In one aspect of the present invention, simulating a nonlinear system is accomplished by first modeling the system and generating parameters that describe the nonlinear system. The system is represented in the frequency domain as an inverse convolution equation (ICE), comprising cascaded convolutions and frequency representations of known and unknown signals. Next, the order of the ICE is determined based upon the degree of nonlinearity in the system. Finally, a general ICE solver algorithm is adapted to the ICE order of the frequency model, and the specific ICE solver algorithm is applied to in order to solve for an unknown signal. In another aspect of the invention, the non-iterative method for simulating nonlinear systems is combined with cross-referenced coordinate (CRC) techniques in order to increase the computational efficiency of the simulation.
