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…
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…
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…
