Modèles de Bruit de Phase pour les Communications Sub-TeraHertz

Abstract : This paper discusses the appropriate choice of phase noise model for sub-THz communications. Two phase noise models are introduced and compared: one correlated, accurate but complex, and another uncorrelated, analytically simpler. The expression of the likelihood ratio enables us to propose an analytical condition to select the best of the two models for a measured oscillator characteristic. It is shown that an uncorrelated Gaussian process is appropriate to model the impact of phase noise in sub-THz systems.
