RIS-Assisted 6G Networks: Challenges and Tradeoffs in Control Standardization
Despite extensive theoretical progress in reconfigurable intelligent surfaces (RISs), practical models and network-level studies remain limited. This paper bridges the gap, exploring RIS-assisted links, proposing a control plane approach, and...
Adaptive and Temporally Consistent Gaussian Surfels for Multi- view Dynamic Reconstruction
We propose AT-GS, a novel method for reconstructing high-quality dynamic surfaces from multi-view videos through per-frame incremental optimization. To avoid local minima across frames, we introduce a unified and adaptive gradient-aware...
Automatic Drywall Analysis for Progress Tracking and Quality Control in Construction
This paper presents an automated drywall analysis method for construction progress and quality assessment using on-site cameras. It integrates a deep learning-based segmentation model to detect and classify drywall elements, with a module to...
Improving Geometric Consistency for 360-Degree Neural Radiance Fields in Indoor Scenarios
NeRFs struggle with low-textured areas, causing "floaters" that reduce realism, especially on featureless surfaces. We propose a method for computing dense depth priors for these areas, using a novel depth loss function and patch regularization...
Experimental Demonstration of a Correlation-Avoidance CMA for Blind Space-Division Multiplexed MIMO Equalization
We demonstrate blind 6x6 adaptive equalization of 32 GBd DP-QPSK 3-mode transmission over a 54 km FMF based on the singularity-free convergence ability of the correlation-avoidance CMA (CA-CMA). The CA-CMA is used for robust pre-convergence in a...
7.75 Gbit/s LiFi Transmitter Using High-Power VCSEL Arrays
We report on a wide-beam LiFi transmitter using multiple VCSEL arrays with digital drivers. We transmit a 3.75 GBd PAM-3 signal at a gross data rate of 5.625 Gbit/s. Single-driver OOK operation yields 7.75 GBd.
Data Governance Framework for Telemetry Sharing
We propose a novel solution using the Eclipse Dataspace Components (EDC) Connector to enable regulated and policy-driven telemetry data sharing in telco ecosystems. We present its architecture, several compatible use-cases, and results validating...
Analysis of Interaction Mechanisms and Intercomparison of Raytracing Tools for Optimizing THz Simulations
This paper compares different raytracing tools in the sub-THz area, to analyze the weight of several different effects, e.g. reflections, diffractions, scattering or atmospheric attenuation, during raytracing simulations for high frequencies. For...
High-quality deepfakes have a heart!
Recent deepfakes preserve subtle heart rate signals, challenging the assumption that rPPG-based detection remains effective. Our study demonstrates that modern deepfake generation techniques encapsulate the heart rate dynamics of source videos,...
