Identification of first order volterra kernels of M-sequence correlation method for nonlinear system

This paper describes a determination method for disappeared Volterra kernel on crosscorrelation function of a nonlinear system by use of a conventional correlation method. In this method, First, we have to search accurate some special higher order kernels on the crosscorrelation function. Second, we resolve the higher kernels to a first order kernels and an approximated coefficient. And the first order kernels and the coefficient reassembled to higher order kernels, and that will be calculated accurate kernel. Lastly, we carried out simulations to confirm of this method.
