Improving the coding speed of erasure codes with polynomial ring transforms
Jonathan Detchart, Jérôme Lacan
Erasure codes are widely used in today's storage systems to cope with failures. Most of them use the finite field arithmetic. In this paper, we propose an implementation and a codi…
Fast Xor-based Erasure Coding based on Polynomial Ring Transforms
Jonathan Detchart, Jérôme Lacan
The complexity of software implementations of MDS erasure codes mainly depends on the efficiency of the finite field operations implementation. In this paper, we propose a method t…
Enhanced Recursive Reed-Muller Erasure Decoding
Alexandre Soro, Jerome Lacan, Vincent Roca +2
Recent work have shown that Reed-Muller (RM) codes achieve the erasure channel capacity. However, this performance is obtained with maximum-likelihood decoding which can be costly…
Estimation of Timing Offsets and Phase Shifts Between Packet Replicas in MARSALA Random Access
Karine Zidane, Jérome Lacan, Mathieu Gineste +3
Multi-replicA decoding using corRelation baSed LocALisAtion (MARSALA) is a recent random access technique designed for satellite return links. It follows the multiple transmission…
Enhanced HARQ for Delay Tolerant Services in Mobile Satellite Communications
Rami Ali Ahmad, Jérôme Lacan, Fabrice Arnal +2
The objective of our paper is to improve efficiency (in terms of throughput or system capacity) for mobile satellite communications. In this context, we propose an enhanced Hybrid…
Improved channel estimation for interference cancellation in random access methods for satellite communications
Karine Zidane, Jérôme Lacan, Marie-Laure Boucheret +1
In the context of satellite communications, random access (RA) methods can significantly increase throughput and reduce latency over the network. The recent RA methods are based on…
Multi-slot Coded ALOHA with Irregular Degree Distribution
Huyen Chi Bui, Jérôme Lacan, Marie-Laure Boucheret
This paper proposes an improvement of the random multiple access scheme for satellite communication named Multislot coded ALOHA (MuSCA). MuSCA is a generalization of Contention Res…
An Enhanced Multiple Random Access Scheme for Satellite Communications
Huyen-Chi Bui, Jérôme Lacan, Marie-Laure Boucheret
In this paper, we introduce Multi-Slots Coded ALOHA (MuSCA) as a multiple random access method for satellite communications. This scheme can be considered as a generalization of th…
Generic Approach for Hierarchical Modulation Performance Analysis: Application to DVB-SH and DVB-S2
Hugo Méric, Jérôme Lacan, Caroline Amiot-Bazile +2
Broadcasting systems have to deal with channel variability in order to offer the best rate to the users. Hierarchical modulation is a practical solution to provide different rates…
Generic Approach for Hierarchical Modulation Performance Analysis: Application to DVB-SH
Hugo Méric, Jérôme Lacan, Caroline Amiot-Bazile +2
Broadcasting systems have to deal with channel diversity in order to offer the best rate to the users. Hierarchical modulation is a practical solution to provide several rates in f…
NCSA: A New Protocol for Random Multiple Access Based on Physical Layer Network Coding
Huyen Chi Bui, Jerome Lacan, Marie-Laure Boucheret
This paper introduces a random multiple access method for satellite communications, named Network Coding-based Slotted Aloha (NCSA). The goal is to improve diversity of data bursts…
FFT-based Network Coding For Peer-To-Peer Content Delivery
Alexandre Soro, Jerome Lacan
In this paper, we propose a structured peer-to-peer (P2P) distribution scheme based on Fast Fourier Transform (FFT) graphs. We build a peer-to-peer network that reproduces the FFT…
FNT-based Reed-Solomon Erasure Codes
Alexandre Soro, Jerome Lacan
This paper presents a new construction of Maximum-Distance Separable (MDS) Reed-Solomon erasure codes based on Fermat Number Transform (FNT). Thanks to FNT, these codes support pra…
Erasure Codes with a Banded Structure for Hybrid Iterative-ML Decoding
Alexandre Soro, Mathieu Cunche, Jerome Lacan +1
This paper presents new FEC codes for the erasure channel, LDPC-Band, that have been designed so as to optimize a hybrid iterative-Maximum Likelihood (ML) decoding. Indeed, these c…
