Abstract
Various impulse response measurement methods are accurate for Hammerstein systems but when a linear filter precedes a static non-linearity, as in a Wiener-Hammerstein system, intermodulation distortion results in undesirable artifacts. In this paper the advantages of the wide maximum length sequence and multiple noise sequences methods are combined to create a method of measuring the diagonal Volterra series expansion of the impulse response of general nonlinear systems that may be seen as an alternative to the existing dynamic convolution method.
