Model-based spectral analysis improves resolution for small data records
Date of Original Version
In situations where high-spectral resolution but with a limited data record is needed, a model-based power spectral density (PSD) estimator can be useful. This article illustrates the use of the autoagressive (AR) model. In particular, the AR estimator is compared to the periodogram.
