Joint Source-Channel Coding for Semantics-Aware Grant-Free Radio Access in IoT Fog Networks
Johannes Dommel, Zoran Utkovski, Osvaldo Simeone +1
A fog-radio access network (F-RAN) architecture is studied for an Internet-of-Things (IoT) system in which wireless sensors monitor a number of multi-valued events and transmit in…

Sparse Signatures with Forward Error Correction Coding for Non-Orthogonal Massive Access
Johannes Dommel, Zoran Utkovski, Petar Popovski +1
In massive connectivity scenarios with short packets, of interest is the regime where users share wireless resources in a non-orthogonal fashion. Small payloads combined with spora…

Joint Source-Channel Coding and Bayesian Message Passing Detection for Grant-Free Radio Access in IoT
Johannes Dommel, Zoran Utkovski, Slawomir Stanczak +1
Consider an Internet-of-Things (IoT) system that monitors a number of multi-valued events through multiple sensors sharing the same bandwidth. Each sensor measures data correlated…
