Coherent网络中的纠错码

网络编码对网络中的传输错误或恶意攻击十分敏感，如果网络拓扑和网络码对于网络的收点和发点都是已知的，这种类型的网络称为Coherent网络。在Coherent网络中，网络汉明重量的概念拉近了网络纠错码和传统纠错码之间的距离，传统纠错码的一些理论和方法有望在将来应用于网络纠错码。类似于传统纠错码，极小距离反映了网络纠错码的纠错能力。利用陪集码理论去描述和研究网络纠错码是一个令人感兴趣的研究方向。

Error Correction Code in Coherent Network

Network coding is very sensitive to the transmission errors or malicious attacks in network. If the knowledge of network topology and network code is known at the source and destination codes, the network is called coherent. In coherent network, the concept of network Hamming weight narrows the gap between network error-correcting codes and classical error-correcting codes. Some theories and methods in classical error-correcting codes have chances to be applied to network error-correcting codes in the future. Similar to classical error-correcting codes, minimum distance characterizes the error-correcting capability of network error-correcting codes. Employing the theories of coset codes to describe and study network error-correcting codes is an interesting research topic.
