Improving Object Delivery Using Application Layer Tornado Codes in DVB-H Systems

Kristian Nybom, Janne Kempe, Jerker Björkqvist, Improving Object Delivery Using Application Layer Tornado Codes in DVB-H Systems. In: Proceedings of the 17th Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC'06), IEEE, 2006.

Abstract:

This paper analyzes the effects of applying application layer
Forward Error Correcting (FEC) coding to a wireless
filecasting system, here represented by DVB-H. We show the
benefit of moving error correcting coding to higher levels in
the data transmission protocol stack. The data is delivered
using a data carousel and the FEC code utilized is a hyper-
Tornado code for which the main characteristics are long
codewords and near linear complexity. Because the hyper-
Tornado code provides internal data interleaving and supports
long code lengths, we can observe a significantly decreased
number of mean data carousel iterations before an error-free
carousel object is received compared to the basic DVB-H
system. This reduction is for the user observed as decreased
download-time, but also provides energy saving in the
receiver due to shorter receiver on-times.
