Abstract

In this paper, we develop a Gaussian basis expansion (GBE)-based phase noise suppression method for coherent optical orthogonal frequency-division-multiplexing (CO-OFDM) systems. The GBE method displays notable advantages over conventional phase noise suppression approaches as it substantially enhances the system tolerance to laser phase noise. These theoretical benefits are further confirmed through numerical simulations conducted in CO-OFDM systems utilizing a 16-quadrature-amplitude-modulation format.
