A new noncausal AR system identification method based on cepstrum
Bin-Ning Chen, Xian‐Da Zhang · 2002
In this paper, a new noncausal AR system identification method based on cepstrum is presented. The proposed method converts the noncausal AR system identification to nonminimum phase MA system identification in the cepstrum domain. The AR order need not be known as a priori, and it is a byproduct of the parameter estimation procedure. An efficient order determination method that can be implemented in an adaptive process is also addressed. Simulation results are presented to show the performance of the new method.
