摘要
创新通信技术在国家重大空间技术开发计划中有着巨大的需求。本文综述了基于网络编码的空间通信技术,旨在探索未来基于网络编码的空间通信技术的可行性和潜力。首先讨论了空间通信的特点,并给出了不同编码方法的概述;详细介绍了基于网络编码的批量稀疏编码(BATS码)创新技术。BATS码作为一种潜在的应用技术可以很好地解决多跳中继网络中严重丢包问题;给出一个BATS码原型设计和实现,实验结果证明BATS码比现有技术具有明显优势;最后,讨论了BATS码在空间通信中的应用前景。
Innovative communication technologies are in great demand in the national space development program. In this paper, space communication with network coding is studied, with the aim of exploring the feasibility and potential of network coding for future space communication. The characteristics of space communication are first discussed, and an overview of different coding based methods is given. As a potentially applicable technology, network coding based Batched Sparse （BATS） code is presented to address the packet loss problem in multi-hop relay networks. In particular, a BATS code prototype is designed and implemented, and the experiment results demonslrale the advantages of BATS codes over alternative technologies. Finally, the prospect of deployment of BATS codes in space communication is discussed.
