Low-complexity Soft-decision LLR Calculations for Next-generation IM-DD Systems with RIN

Felipe Villenas, Yunus Can Gültekin, Alex Alvarado

The demand for higher speeds in intra-data center interconnects will eventually require high-order pulse amplitude modulation (PAM) combined with soft-decision (SD) forward error c…

Characterizing Nonlinearities in IM-DD Links via the Best Linear Approximation: Distortion Analysis and Modulation Optimization

Sebastian Fraga Fernández, Leonardo Minelli, Fernando de Bernardinis +3

We use the best linear approximation (BLA) to characterize nonlinearities in IM-DD links. The orthogonal nonlinear distortion is shown to be non-Gaussian. The BLA is used to approx…

High-throughput Low-latency Hardware Implementation of BCH Decoders

Jasper Lagendijk, Wenqing Song, Yunus Can Gültekin +3

Two well-known decoding algorithms for BCH codes are conventional decoding, based on the Berlekamp-Massey algorithm in combination with Chien search, and direct decoding, which use…

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…

Optical Communications with Relative Intensity Noise: Channel Modeling and Information Rates

Felipe Villenas, Yunus Can Gültekin, Alex Alvarado

We consider optical communications with intensity modulation and direct detection affected by laser relative intensity noise (RIN). Starting from a continuous-time waveform model,…

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…
