Abstract：Since its wide coverage area, data broadcast is the major service of spatial system. However, due to the long distance and the complex, varied climate, data transmission suffers large round-trip-time and poor error performance. In order to achieve better performance, based on fountain codes and the feedback information, a novel and efficient data transmission strategy is proposed. Compared with typical protocols, the proposed strategy uses the feedback information to estimate the channel erasure probability. Besides, a weighted packet chosen vector is introduced into the fountain encoder to ensure the lost packets retransmitted in the order of the total consideration of their lost probability and the number of users which need a retransmission. Simulation results show that by the proposed scheme users can receive the data packets reliably while the total number of transmitted packets is less than the traditional protocols.
