We propose and experimentally demonstrate an optical network architecture that uses
wideband optical frequency comb (OFC) sources synchronized with transmitted network …

While probabilistic constellation sha** (PCS) enables rate and reach adaption with finer
granularity [1](Cho and Winzer, 2009), it imposes signal processing challenges at the …

We propose a novel closed-form time-domain (TD) Volterra series nonlinear equalizer
(VSNE) for the mitigation of Kerr-related distortions in polarization-multiplexed (PM) …

By deriving the physical model of the system, which includes definitions of both state
variables and measurement equations, we apply an extended Kalman filter to Stokes space …

We experimentally assess the performance versus complexity tradeoff of advanced split-step
and Volterra-based digital backpropagation (DBP) techniques, applied to a WDM (75-GHz …

We demonstrate a real-time coherent optical receiver based on a single field programmable
gate array (FPGA) chip. To strike the balance between the performance and hardware …

Optical superchannels and digital nonlinear mitigation are key technology options to be
considered for the deployment of next-generation optical 400G transmission systems. In this …

The RDE for M-ary QAM equalisation is modified using a low-complexity probabilistic update
algorithm. Performance is investigated in simulation and experiment for 8 GBd DP-64QAM …
