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.
