IEEE Pacific Rim Conference on Communications, Computers and Signal Processing June 1st - 2nd, 1989 Discrete Frequency-domain Modeling and Measuring of Mildly Nonlinear of Volterra Transfer functions with a set of Special Sinusoid Signals(*)

This paper gives a method to measure first/second Volterra Kernels in frequencydomain.When input signal is many-tones sinusoid ,the Volterra modeling of nonlinear system in descrete frequency domain is given .According this model and carefully choosing input frequencies, we can measure the first/second Volterra kernels at a time with many points.The computer algorithm is proposed and the simulation results are reached to show the efficiency of this method .
