Improving Conversation Quality for VoIP Through Block Erasure Coding [article]

Bobak McCann, Kerry Fendick, Aaron David, Antonio DeSimone, Steven Handy
2019 arXiv   pre-print
The benefits for conversational voice quality of erasure coding attributable to its reduction in packet loss rates are widely appreciated.  ...  When block erasure coding is used, our analysis shows how those benefits are reduced or even eliminated by increases in delays and in a measure of burstiness of packet loss.  ...  ACKNOWLEDGMENT We thank Brian Adamson from the Navy Research Laboratory for help in understanding NRL's NORM implementation.

A throughput-delay trade-off in packetized systems with erasures

M. Vehkapera, M. Medard
2005 Proceedings. International Symposium on Information Theory, 2005. ISIT 2005.  
In this paper we propose an information theoretic framework for studying coding and throughput optimization for multi-layered packet transmission systems.  ...  The proposed scheme provides also means for investigating important physical layer phenomena, such as, channel model and lower layer error correction coding in the packet erasure models.  ...  The latter provides one possible way to take into account also the interference in multiple-access for the erasure network models [9] , [10] .  ...

Relaying a fountain code across multiple nodes

Ramakrishna Gummadi, R.S. Sreenivas
2008 2008 IEEE Information Theory Workshop  
The problem of designing a rateless erasure coding scheme in the network case for on-the-fly recoding is important, as relaying the data over multiple nodes is fundamentally useful in a network.  ...  With this motivation, we consider packet level coding on a line network (or a tree) of discrete memoryless erasure channels (with potentially unlimited nodes), and propose a rateless coding scheme with  ...  For erasure coding on a network, Random Linear Coding (RLC) involves combining packets according to a uniformly random choice of each packet taken over a finite field( [3] ).  ...
