NEW APPROACH TO FIR SYSTEM IDENTIFICATION USING HIGHER ORDER CUMULANTS
|
Abstract:
The problem of identifying the parameters of the nonminimum phase FIR system from the cumulants of noisy output samples is addressed. A novel method by using higher-order cumulants is proposed with the following advantages. (1) Flexibility: the method employs two arbitrary adjacent order cumulants of output. (2) Linearity: the formulation in the method is linear with respect to the unknowns, unlike the existing cumulant-based algorithms. The post-processing is thus avoided.
