Virtual Submodule Concept Applied to the Modular Multilevel Converter

Drazen Dujic, Alexandre François Christe

The design phase of a modular multilevel converter (MMC) needs to be supported by suitable tools for the submodule loss evaluation. This paper proposes a fast MMC cell loss calculation based on the virtual submodule (VSM) concept. Compared to other propose ...

Robust Distributed Estimation by Networked Agents

Ali H. Sayed, Ali Zoubir

Diffusion adaptive networks tasked with solving estimation problems have attracted attention in recent years due to their reliability, scalability, resource efficiency, and resilience to node and link failure. Diffusion adaptation strategies that are based ...

Strain engineering a 4a x root 3a charge-density-wave phase in transition-metal dichalcogenide 1T-VSe2

Donat Fabian Natterer

We report a rectangular charge density wave (CDW) phase in strained 1T-VSe2 thin films synthesized by molecular beam epitaxy on c-sapphire substrates. The observed CDW structure exhibits an unconventional rectangular 4a x root 3a periodicity, as opposed to ...

Broadband Topological Non-Reciprocity in Time-Floquet Metamaterials

Romain Christophe Rémy Fleury

We introduce and discuss time-Floquet metamaterials, or artificial media possessing a double periodicity both in space and time. They can be obtained from a regular crystal by periodically modulating in time the physical properties of each unit cell, leadi ...

Learning Wi-Fi Performance

Julien Pierre Sacha Herzen, Nidhi Hegde

Accurate prediction of wireless network performance is important when performing link adaptation or resource allocation. However, the complexity of interference interactions at MAC and PHY layers, as well as the vast variety of possible wireless configurat ...

On Secure and Precise IR-UWB Ranging

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski, Manuel Flury

To provide high ranging precision in multipath environments, a ranging protocol should find the first arriving path, rather than the strongest path. We demonstrate a new attack vector that disrupts such precise Time-of-Arrival (ToA) estimation, and allows ...

Layered Detection and Decoding in MIMO Wireless Systems

Andreas Peter Burg, Nicholas Alexander Preyss, Christoph Studer

Iterative detection and decoding (IDD) in multiple-input multiple-output (MIMO) wireless systems is known to achieve near channel capacity. The high computational complexity of IDD, however, poses signiﬁcant challenges for practical implementations (in ter ...

High-resolution Brillouin fiber sensing using random phase coding of the pump and probe waves

Luc Thévenaz, Nikolay Primerov

Distributed temperature measurements with 1.2 cm resolution based on stimulated Brillouin scattering (SBS) in standard fibers are reported. High resolution is achieved by phase-coding both pump and probe waves with a high-rate, pseudo-random binary phase c ...

Approximate Capacity of a Class of Gaussian Interference-Relay Networks

Christina Fragouli, Suhas Diggavi

In this paper, we study a Gaussian relay-interference network, in which relay (helper) nodes are to facilitate competing information flows between different source-destination pairs. We focus on two-stage relay-interference networks where there are weak cr ...

Cross-Layer Based Analysis of Multi-Hop Wireless Networks

Tarik Tabet

In this work, we revisit classical packet radio networks with a modern treatment of physical-layer (PHY) procedures, medium-access (MAC) and geographic channel-driven routing protocols. Our network model assumes that nodes are randomly distributed on the p ...
