Sparse-Graph AL-FEC Solutions for IP Datacasting in DVB-H

Kristian Nybom, Dejan Vukobratovic, Jerker Björkqvist, Sparse-Graph AL-FEC Solutions for IP Datacasting in DVB-H. In: IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB 2009), 2009.

Abstract:

DVB-H is an IP-based wireless broadcast technology in which users are
offered, among other services, the IP datacast (IPDC) service for downloading
broadcasted files to their mobile terminals. In this paper, we explore different
AL-FEC solutions providing simple and efficient file delivery. Our investigation
is focused on recently popular classes and design methods of sparse-graph
codes decoded using the iterative decoding algorithm. We provide performance
comparisons of various possible AL-FEC schemes in a simulated DVB-H
environment. The benefits and drawbacks of different sparse-graph AL-FEC
solutions are discussed.
