Network-Coding-Based Broadcasting Retransmission Approach in Satellite Communications

摘要：

　　In satellite communications,it is often necessary to broadcast large data to terrestrial users.Because the satellite channel is a typical fading channel,packets cant be correctly received.Therefore,retransmission is necessary.This paper proposes a network-coding-based broadcasting retransmission approach,whose key idea is to combine different lost packets with network coding to achieve minimum number of retransmission.Simulation results indicate that compared with existing approaches,network-coding-based broadcasting retransmission approach can effectively reduce average number of transmissions.
