Abstract: Based
on the deduction of the C parameter estimation, a new method to
estimate C Parameters from the AR parameters of the ARMA model
and auto-related function is proposed, the method reduces the
computation complexity of the conventional interative algorithm
in MA parameter estimation, thus make the algorithm of ARMA
model spectral estimation simpler. On account of this method, a
new algorithm of spectrum analysis is put forward, computer
simulation indicates that the proposed spectrum algorithm has
the merits of few sidelobes and high resolution. And the
algorithm is very useful to the diagnosis of machinery failure.
Key words: Spectrum Estimation
Spectrum Resolution
