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...
