Analyse spectrale des signaux aléatoires bivariés

Abstract : We propose a new framework to spectral analysis of stationary bivariate signals seen as complex signals. In constrast to existing approaches, we show a natural link between statistical objects and physical parameters. The approach relies on the quaternion spectral density of a stationary bivariate signal. An original decomposition of such signals into polarized and unpolarized components is presented. The proposed approach is illustrated on a toy example.
