Volterra kernel estimation for mildly nonlinear amplifiers
J.G. McRory, R.H. Johnston · Electronics Letters · 1993
The linear, third and fifth order Volterra kernels for two mildly nonlinear amplifiers have been estimated using common RF laboratory equipment. The estimation U made through a series of least square curve fits between measured data and nonlinear transfer functions. The estimation is validated through the comparison between measured and predicted IM3 distortion levels
