Abstract:
In this paper, higher-order stat ist ics is applied to identify linear time-invariant no nminimum phase FIR sy stem. For a nonminimum phase FIR sy stem w ho se input data is no ng aussian and not symmet rically dist ributed, w hen only output data ( may be noisy ) is available, a new algor ithm is presented using 3rd-o rder and 4th-order cumulant of the data to est imate the system. As compar ed with GM and T alg orithm, the new alg orithm is bet ter w hen data is interfered w ith colored gaussian noise.
