Spectral Analysis (Parametric and Non-Parametric Digital Methods)

In Signal Processing, the concepts of frequency, which are usually referred to as "spectral" concepts, are omnipresent. The transition from analogue methods to the use of digital tools in spectral analysis was first achieved by simple adaptation of the classical analogue tools that had long been used previously. However, beyond the simple quest of methods with better frequency resolution, it has been possible to develop specific digital tools based on parametric modeling. This book deals with these parametric methods, first discussing those based on time series models, Capon?s method and its variants, and then estimators based on the notions of sub-spaces. However, the book also deals with the traditional "analogue" methods, now called non-parametric methods, which are still the most widely used in practical spectral analysis.
