Error Floor Analysis of Coded Slotted ALOHA over Packet Erasure Channels
Mikhail Ivanov, Fredrik Brannstrom, Alexandre Graell i Amat +1
We present a framework for the analysis of the error floor of coded slotted ALOHA (CSA) for finite frame lengths over the packet erasure channel. The error floor is caused by stopp…
Efficiency Analysis of Decoupled Downlink and Uplink Access in Heterogeneous Networks
Katerina Smiljkovikj, Liljana Gavrilovska, Petar Popovski
This paper analyzes two-tier heterogeneous cellular network with decoupled downlink and uplink access. The basic performance benefits of uplink/downlink decoupling have been recent…
A Stochastic Geometry Framework for LOS/NLOS Propagation in Dense Small Cell Networks
Carlo Galiotto, Nuno K. Pratas, Nicola Marchetti +1
The need to carry out analytical studies of wireless systems often motivates the usage of simplified models which, despite their tractability, can easily lead to an overestimation…
Secure Communication with a Wireless-Powered Friendly Jammer
Wanchun Liu, Xiangyun Zhou, Salman Durrani +1
In this paper, we propose to use a wireless-powered friendly jammer to enable secure communication between a source node and destination node, in the presence of an eavesdropper. W…
Manycore processing of repeated range queries over massive moving objects observations
Francesco Lettich, Salvatore Orlando, Claudio Silvestri +1
The ability to timely process significant amounts of continuously updated spatial data is mandatory for an increasing number of applications. Parallelism enables such applications…
Modeling Populations of Thermostatic Loads with Switching Rate Actuation
Luminita Cristiana Totu, Rafael Wisniewski, John Leth
We model thermostatic devices using a stochastic hybrid description, and introduce an external actuation mechanism that creates random switch events in the discrete dynamics. We th…
Normally Regular Digraphs
Leif K Jørgensen
A normally regular digraph with parameters is a directed graph on vertices whose adjacency matrix satisfies the equation . This…
Reengineering GSM/GPRS Towards a Dedicated Network for Massive Smart Metering
Germán Corrales Madueño, Čedomir Stefanović, Petar Popovski
GSM is a synonym for a major success in wireless technology, achieving widespread use and high technology ma- turity. However, its future is questionable, as many stakeholders indi…
More results on the number of zeros of multiplicity at least r
Olav Geil, Casper Thomsen
We consider multivariate polynomials and investigate how many zeros of multiplicity at least they can have over a Cartesian product of finite subsets of a field. Here r is any…
Sign-Compute-Resolve for Random Access
Jasper Goseling, Cedomir Stefanovic, Petar Popovski
We present an approach to random access that is based on three elements: physical-layer network coding, signature codes and tree splitting. Upon occurrence of a collision, physical…
Perfect and Stable Hybrid Glasses from Strong and Fragile Metal-Organic Framework Liquids
T. D. Bennett, Jin-Chong Tan, Y. Z. Yue +8
Hybrid glasses connect emerging fields of metal-organic frameworks (MOFs) with the glass-formation, amorphization, and melting processes of these structurally diverse and chemicall…
Model Reduction of Linear Switched Systems by Restricting Discrete Dynamics
Mert Bastug, Mihaly Petreczky, Rafael Wisniewski +1
We present a procedure for reducing the number of continuous states of discrete-time linear switched systems, such that the reduced system has the same behavior as the original sys…
Random Access Protocols with Collision Resolution in a Noncoherent Setting
Zoran Utkovski, Tome Eftimov, Petar Popovski
Wireless systems are increasingly used for Machine-Type Communication (MTC), where the users sporadically send very short messages. In such a setting, the overhead imposed by chann…
Generation and Analysis of Constrained Random Sampling Patterns
Jacek Pierzchlewski, Thomas Arildsen
Random sampling is a technique for signal acquisition which is gaining popularity in practical signal processing systems. Nowadays, event-driven analog-to-digital converters make r…
A review of the characteristics of 108 author-level bibliometric indicators
Lorna Wildgaard, Jesper W. Schneider, Birger Larsen
An increasing demand for bibliometric assessment of individuals has led to a growth of new bibliometric indicators as well as new variants or combinations of established ones. The…
Dirac model of electronic transport in graphene antidot barriers
M. R. Thomsen, S. J. Brun, T. G. Pedersen
In order to use graphene for semiconductor applications, such as transistors with high on/off ratios, a band gap must be introduced into this otherwise semimetallic material. A pro…
Relative generalized Hamming weights of q-ary Reed-Muller codes
Olav Geil, Stefano Martin
Coset constructions of -ary Reed-Muller codes can be used to store secrets on a distributed storage system in such a way that only parties with access to a large part of the sys…
Analysis of the Decoupled Access for Downlink and Uplink in Wireless Heterogeneous Networks
Katerina Smiljkovikj, Petar Popovski, Liljana Gavrilovska
Wireless cellular networks evolve towards a heterogeneous infrastructure, featuring multiple types of Base Stations (BSs), such as Femto BSs (FBSs) and Macro BSs (MBSs). A wireless…
Variational approach for spatial point process intensity estimation
Jean-François Coeurjolly, Jesper Møller
We introduce a new variational estimator for the intensity function of an inhomogeneous spatial point process with points in the -dimensional Euclidean space and observed within…
A Characterization of the Minimal Average Data Rate that Guarantees a Given Closed-Loop Performance Level
Eduardo~I. Silva, Milan S. Derpich, Jan Ostergaard +1
This paper studies networked control systems closed over noiseless digital channels. By focusing on noisy LTI plants with scalar-valued control inputs and sensor outputs, we derive…
Spectral edge regularity of magnetic Hamiltonians
Horia D. Cornean, Radu Purice
We analyse the spectral edge regularity of a large class of magnetic Hamiltonians when the perturbation is generated by a globally bounded magnetic field. We can prove Lipschitz re…
