End-to-End Modelling of Earthquake-Induced Polarisation Perturbations in Submarine Optical Fibres
Rick M. Butler, José Núñez-Kasaneva, Gabriele Liga +3
We present an end-to-end model of earthquake-perturbed signal propagation in submarine fibres. Ground displacements are converted to fibre strain via ocean pressure, and injected i…
The Memory-Enhanced Gaussian Noise (MEGN) Model for Fiber-Optic Channels
Kaiquan Wu, Gabriele Liga, Marco Secondini +5
The enhanced Gaussian noise (EGN) model is widely used for estimating the nonlinear interference (NLI) power accumulated in coherent fiber-optic transmission systems. Given a fixed…
Syndrome Adaptive Gain Control for Min-Sum Decoding of Quantum LDPC Codes
Hernan Cordova, Alexios Balatsoukas-Stimming, Yunus Can Gültekin +2
Min-Sum (MS) decoding is a popular low-complexity alternative to belief propagation (BP), retaining only the minimum incoming message magnitude during check-node (CN) processing, a…
A Fully Open-source Implementation of an Analog 8-PAM Demapper for High-speed Communications
Mohamed Aiham Hemza, Alex Alvarado, Krzysztof Herman +1
Spectrally-efficient communication systems rely on the use of multi-level modulation formats. At the receiver side, a demodulator is often used to extract soft information about th…
On LLR Mismatch in Belief Propagation Decoding of Overcomplete QLDPC Codes
Hernan Cordova, Alexios Balatsoukas-Stimming, Gabriele Liga +2
Belief propagation (BP) decoding of quantum low density parity check (QLDPC) codes is often implemented using overcomplete stabilizer (OS) representations, where redundant parity c…
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…
