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…
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…
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…
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…
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…
New Quantum Codes from Evaluation and Matrix-Product Codes
Carlos Galindo, Fernando Hernando, Diego Ruano
Stabilizer codes obtained via CSS code construction and Steane's enlargement of subfield-subcodes and matrix-product codes coming from generalized Reed-Muller, hyperbolic and affin…
Compressed Sensing Based Direct Conversion Receiver With Interference Reducing Sampling
Jacek Pierzchlewski, Thomas Arildsen, Torben Larsen
This paper describes a direct conversion receiver applying compressed sensing with the objective to relax the analog filtering requirements seen in the traditional architecture. Th…
Using Wireless Network Coding to Replace a Wired with Wireless Backhaul
Henning Thomsen, Elisabeth de Carvalho, Petar Popovski
Cellular networks are evolving towards dense deployment of small cells. This in turn demands flexible and efficient backhauling solutions. A viable solution that reuses the same sp…
Characterization of Coded Random Access with Compressive Sensing based Multi-User Detection
Yalei Ji, Cedomir Stefanovic, Carsten Bockelmann +2
The emergence of Machine-to-Machine (M2M) communication requires new Medium Access Control (MAC) schemes and physical (PHY) layer concepts to support a massive number of access req…
Zero-Outage Cellular Downlink with Fixed-Rate D2D Underlay
Nuno K. Pratas, Petar Popovski
Two of the emerging trends in wireless cellular systems are Device-to-Device (D2D) and Machine-to-Machine (M2M) communications. D2D enables efficient reuse of the licensed spectrum…
Fulcrum Network Codes: A Code for Fluid Allocation of Complexity
Daniel E. Lucani, Morten V. Pedersen, Diego Ruano +4
This paper proposes Fulcrum network codes, a network coding framework that achieves three seemingly conflicting objectives: (i) to reduce the coding coefficient overhead to almost…
Relative generalized Hamming weights of one-point algebraic geometric codes
Olav Geil, Stefano Martin, Ryutaroh Matsumoto +2
Security of linear ramp secret sharing schemes can be characterized by the relative generalized Hamming weights of the involved codes. In this paper we elaborate on the implication…
Exploiting Regional Differences: A Spatially Adaptive Random Access
Dong Min Kim, Seong-Lyun Kim
In this paper, we discuss the potential for improvement of the simple random access scheme by utilizing local information such as the received signal-to-interference-plus-noise-rat…
Block-Fading Channels with Delayed CSIT at Finite Blocklength
Kasper Fløe Trillingsgaard, Petar Popovski
In many wireless systems, the channel state information at the transmitter (CSIT) can not be learned until after a transmission has taken place and is thereby outdated. In this pap…
Delayed Channel State Information: Incremental Redundancy with Backtrack Retransmission
Petar Popovski
In many practical wireless systems, the Signal-to-Interference-and-Noise Ratio (SINR) that is applicable to a certain transmission, referred to as Channel State Information (CSI),…
Distributed Remote Vector Gaussian Source Coding for Wireless Acoustic Sensor Networks
Adel Zahedi, Jan Ostergaard, Soren Holdt Jensen +2
In this paper, we consider the problem of remote vector Gaussian source coding for a wireless acoustic sensor network. Each node receives messages from multiple nodes in the networ…
