A New Analytical Model of Phase Noise in Communication Systems

Paper i proceeding, 2022

We consider the phase noise affecting communication systems, where local oscillators are employed to obtain a reference signal for frequency and phase synchronizations. We try to fill the gap between measurements and analytical models, in case of free-running and phase-locked oscillators. In particular, we propose a closed form expression for the power spectral density of the phase noise described by few parameters that are explicitly linked to the oscillator measurements. We also propose an analytical model for the oscillator power spectral density.
