Abstract

In this letter, we study wireless broadcast schemes based on online fountain codes. We first propose and analyze an online fountain code based-broadcast scheme, where the coded symbol degree is updated based on the decoding states of all receivers. Then we propose and analyze an improved broadcast scheme by taking advantage of the received coded symbols that are not immediately decodable. Simulation results demonstrate that our proposed scheme has better performance compared to other broadcast schemes based on feedback fountain codes.
