中文摘要： 随机卷积网络编码不但可以解决网络编码的编码域估计困难和对未知拓扑的适应问题，而且编码操作简单，在译码时延和存储消耗方面有很大节省，是一类具有重要理论和工程应用意义的线性网络编码。因此，研究和开发随机卷积网络编码的应用是推进网络编码实用进程很重要的一步。但要在无线通信中实现它还有很多问题需解决，比如如何克服传输时延和干扰，如何应对丢包和敌人攻击等。本项目旨在解决这些问题，实现适应无线网络的低复杂度、安全和可纠错的卷积网络编码。重点研究：结合无线网络编码的传输特性，利用移位寄存器实现随机卷积网络编码的编、译码方案；针对丢包及易受攻击特点，设计自适应的可靠且高效的卷积网络编码；深入研究多信源卷积网络编码，建立多用户协同工作的无线传输系统。相信本项目的研究将为卷积网络编码实际应用于新一代通信网络提供理论基础和技术支持。

英文摘要： Randomized convolutional network coding, which not only solves the field size choosen problem and adapts to unknown topology, but also has advantages in encoding complexity, decoding delay and memeory use, is one type of linear network coding which plays an important role in both theory and engineering applications. Therefore, the study and development on randomized convolutional network coding and its applications are very important to realize network coding. However, many issues are in the way of its implementation in wireless communications, such as how to overcome transmission delay and inference, and how to deal with packet loss and attacks, etc. Under the support of this project, our goal is to propose and implement a series of error correction and secure convolutional network codes with low complexity based on the characteristics of wireless network. The research is focused on: Combined with the transmission characteristic of wireless communications, we implement a set of random convolutional network coding through shift register; Against packet loss and attack, we design an adaptive efficient and reliable convolutional network codes; We also study multi-user convolutional network coding, and build an multi-user collaborative communication system with network coding in wireless networks. We believe that
