A complete digital twin-assisted lightpath operation workflow for multiband optical networks is proposed for assured performance and reliable surveillance. Accurate performance estimation and prompt degradation detection through continuous model...
Machine Learning Assisted Digital Twin Framework for Improved EDFA Gain and QoT Estimation
We propose a hybrid digital twin using GNPy with ML-assisted EDFA models for accurate QoT estimation. The models achieve sub-0.1dB gain error, enhancing data ef ficiency and improving end-to-end lightpath signal-to-noise ratio estimation within...
Digital Self-Interference Cancellation Using Kernel Adaptive Filtering in Hilbert Spaces
Can full-duplex radios cancel their own transmissions fast enough for real-world use? This work develops a multi-kernel adaptive canceller that tracks nonlinear self-interference under changing conditions and demonstrates more than 50 dB...
AI-Assisted Frameworks for Sensing-Related Reporting in Integrated Sensing and Communication
In ISAC systems, the type of information exchange is important. Future ISAC systems require efficient information exchange when sensing is split between the user device (UE) and the base station (BS). We propose AI and non-AI frameworks for...
Dynamic presentation in 3D modulates face similarity judgements: a human-aligned encoding model approach
Abstract Face perception dynamically unfolds in three-dimensional space, yet, experimental paradigms predominantly rely on static 2D images, limiting insights into real-world face processing. We conducted a pre-registered study comparing face...
Cellular, Cell-less, and Everything in Between: A Unified Framework for Utility Region Analysis in Wireless Networks
This study connects the geometry of network utility regions -- such as SINR and achievable rates -- to the concept of nonlinear spectral radius. In doing so, it reveals when scheduling offers no extra gains and identifies regimes in which...
Linewidth Narrowing of InP-Based Lasers by Self-Injection Locking With a Monolithically Integrated Ring Resonator
A new monolithically integrated self-injection locking scheme, based on a ring resonator and a reflector, is demonstrated for InP lasers. We analyze and compare three different configurations, focusing particularly on the Lorentzian linewidth: an...
