A new AL-FEC coding scheme with limited feedback

Abstract

For the next generation mobile video broadcasting, especially in-band solutions that serves the mobile devices, a limited feedback scheme via cellular channel polling is feasible to give accurate real-time information on the broadcast receivers' channel erasure rate, and decoding buffer status. In this work, we propose an AL-FEC coding degree scheme based on this feedback, to achieve a better decode efficiency and save the code redundancy. Simulation results demonstrate the effectiveness of this solution, and open up new opportunities in the next generation broadcasting system design.
