Caching in Heterogeneous Satellite Networks with Fountain Codes
Estefanía Recayte, Francisco Lázaro, Gianluigi Liva
In this paper we investigate the performance of caching schemes based on fountain codes in a heterogeneous satellite network. We consider multiple cache-aided hubs which are connec…
Reliability-Latency Performance of Frameless ALOHA with and without Feedback
Francisco Lázaro, Čedomir Stefanović, Petar Popovski
This paper presents a finite length analysis of multi-slot type frameless ALOHA based on a dynamic programming approach. The analysis is exact, but its evaluation is only feasible…
Symbol Message Passing Decoding of Nonbinary Low-Density Parity-Check Codes
Francisco Lázaro, Alexandre Graell i Amat, Gianluigi Liva +1
We present a novel decoding algorithm for q-ary low-density parity-check codes, termed symbol message passing. The proposed algorithm can be seen as a generalization of Gallager B…
From 5G to 6G: Has the Time for Modern Random Access Come?
Federico Clazzer, Andrea Munari, Gianluigi Liva +3
This short paper proposes the use of modern random access for IoT applications in 6G. A short overview of recent advances in uncoordinated medium access is provided, highlighting t…
Caching at the Edge with LT codes
Estefanía Recayte, Francisco Lázaro, Gianluigi Liva
We study the performance of caching schemes based on LT under peeling (iterative) decoding algorithm. We assume that users ask for downloading content to multiple cache-aided trans…
A Droplet Approach Based on Raptor Codes for Distributed Computing With Straggling Servers
Albin Severinson, Alexandre Graell i Amat, Eirik Rosnes +2
We propose a coded distributed computing scheme based on Raptor codes to address the straggler problem. In particular, we consider a scheme where each server computes intermediate…
