| Abstract: | The theory of paramctric spectral analysis and its use in NMR data processing field was presented.Then,an efficient method for parameter computing,called High-order Yule-Walker Equations (HOYWE) method was introduced. This is a high precision method for computing the coefficients of the AR part of an ARMA model,therefore the resulting spectrum is very similar to the corresponding true spectrum,In order to facilitate the using of this new method, a simple but effective strategy for choosing the true number of complex exponential components in signal was proposed. The computer simulation tests have justified the applicability of this strategy and the HOYWE method. |
