Identification of cubic systems using higher order moments of i.i.d. signals
Ching-Hsiang Tseng, Edward J. Powers · IEEE Transactions on Signal Processing · 1995
A simple method for estimating the Volterra kernels of cubic systems with a zero-mean i.i.d. input is presented. This method significantly reduces the computational complexity of Volterra kernel estimation compared to the non-i.i.d. and non-Gaussian input case.>
