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...
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...
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...
LiFi for Industry 4.0: Main Features, Implementation and Initial Testing of IEEE Std 802.15.13
The recently approved IEEE standard 802.15.13 defines a deterministic medium access scheme with dynamically allocated time slices and two ways of coding and modulation for industrial light communication. We present our work on prototyping the...
Multi-Gbit/s LiFi Experiments with a VCSEL TX and an Enhanced Pulsed Modulation PHY
Enhancing an OOK-based PHY for LiFi, we show that the large bandwidth, high power, and low energy consumption of low-cost VCSEL arrays combined with SFP drivers can be utilized to reach Multi-Gbit/s data rates and enable user mobility in large...
On the Optimal Performance of Distributed Cell-Free Massive MIMO with LoS Propagation
We investigate the capability of team MMSE technique in enhancing distributed beamforming for dense user-centric cell free massive MIMO networks. Considering the anticipated ultra-dense nature of cell-free massive MIMO networks and the...
Doppler Power Spectrum in Channels with von Mises-Fisher Distribution of Scatterers
This paper presents a closed-form expression for Doppler spectrum in mobile wireless channels with von Mises-Fisher (vMF) angular distribution of scatters. The obtained result is employed to analyze the impact of the vMF scattering parameters...
Semantic Security with Infinite-Dimensional Quantum Eavesdropping Channel
We investigate the semantic security of classical and quantum communication channels in the presence of infinite-dimensional side channels. A new method for security proofs is developed, which allows to derive finite block-length results in the...
Joint Waveform Design for Communication and Sensing with Adjustable PAPR
This paper proposes a dual-functional waveform design for integrated sensing and communication systems under adjustable peak-to-average-power-ratio constraints.
Towards Infrastructure-assisted WiFi Rate Adaptation for Converged Networks with Morpheus
The paper discusses a novel framework to integrate heterogeneous Radio Access Technologies (RATs) with the 5G O-RAN for coordination and joint optimization. As an example, it lays out the architecture of a WiFi Radio Intelligent Controller (RIC)...
