On the Capacity of Correlated Phase-Noise Channels: An Electro-Optic Frequency Comb Example
Mohammad Farsi, Hamdi Joudeh, Gabriele Liga +3
The capacity of a discrete-time channel with correlated phase noises is investigated. In particular, the electro-optic frequency comb system is considered, where the phase noise of…
Pilot Distributions for Phase Noise Estimation in Electro-Optic Frequency Comb Systems
Mohammad Farsi, Magnus Karlsson, Erik Agrell
We explore the optimal pilot positioning for phase tracking in electro-optic frequency comb setups. We show that, in contrast to previous results for regular multichannel systems,…
Learning to Extract Distributed Polarization Sensing Data from Noisy Jones Matrices
Mohammad Farsi, Christian Häger, Magnus Karlsson +1
We consider the problem of recovering spatially resolved polarization information from receiver Jones matrices. We introduce a physics-based learning approach, improving noise resi…
Polarization Tracking in the Presence of PDL and Fast Temporal Drift
Mohammad Farsi, Christian Häger, Magnus Karlsson +1
In this paper, we analyze the effectiveness of polarization tracking algorithms in optical transmission systems suffering from fast state of polarization (SOP) rotations and polari…
Capacity Bounds under Imperfect Polarization Tracking
Mohammad Farsi, Magnus Karlsson, Erik Agrell
In optical fiber communication, due to the random variation of the environment, the state of polarization (SOP) fluctuates randomly with time leading to distortion and performance…
