Abstract

Recently, online fountain codes attract much attention as the online property is enhanced by introducing feedback. In this paper, we propose two improvements to Heuristic Table Lookup based on Overhead (HTLO), i.e., Integration based Overhead Calculation (IO) and Flexible Selection Strategy (FSS), and introduce our new feedback strategy IO-FSS-HTLO. In the proposed scheme, the degree of coded symbols and corresponding feedback points are selected to achieve lower overhead when the number of feedback transmissions is limited. Results show that IO-FSS-HTLO could achieve better overhead performance under limited feedback scenarios compared to HTLO.
