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…
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…
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…
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…
Nonlinearity Cancellation Based on Optimized First Order Perturbative Kernels
Alex Alvarado, Astrid Barreiro, Gabriele Liga
The potential offered by interference cancellation based on optimized regular perturbation kernels of the Manakov equation is studied. Theoretical gains of up to 2.5 dB in effectiv…
Rate-adaptive Reconciliation for Experimental Continuous-variable Quantum Key Distribution with Discrete Modulation over a Free-space Optical Link
Kadir Gümüş, João dos Reis Frazão, Vincent van Vliet +8
Continuous-variable quantum key distribution (CV-QKD) has been proposed as a method for securely exchanging keys to protect against the security concerns caused by potential advanc…
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…
