| Zusammenfassung: | The invention discloses a high-throughput satellite formation data transmission method based on network coding. The high-throughput satellite formation data transmission method comprises a transmission satellite and K receiving satellites, wherein K is larger than 1; each receiving satellite feeds back a decoded data packet state to the transmission satellite according to a competitive feedback mechanism after receiving a coded data packet of the transmission satellite; and the transmission satellite adjusts sliding steps of a sliding window according to the data packet state, selecting a next group of coded data packets and transmits the next group of coded data packets to the receiving satellites. Through transmission of the data packets in the manner, retransmission times can be reduced effectively; feedback times are reduced; and network throughput is increased.
本发明公开了种基于网络编码的高吞吐量卫星编队数据传输方法，包括个发送卫星和K个接收卫星，其中，K＞1，每个接收卫星接收到发送卫星的编码数据包后根据竞争反馈机制向发送卫星反馈解码出的数据包状态，发送卫星根据数据包状态调整滑动窗口的滑动步数选取下组编码数据包发送至接收卫星。利用这个方式发送数据 |
