| 中文摘要:近年来,网络编码作为提高通信系统吞吐量一种手段。在多播的通信网络，网络中各个传送节点结合动态变化的网络情况，对不同信息流的数据包进行编码处理，从而减轻局部节点的阻塞，提高了整个通信系统的性能。文章主要工作要体现在典型无线通信网络中，引入动态网络编码调度算法，提高无线通信系统的网络编码增益和系统吞吐量；探讨在自适应无线通信系统下，如何适当的使用自适应技术，使得动态网络编码调度算法的作用发挥到最大。各个节点间的发送端更应选取适合的自适应技术,来提高无线通信系统性能。通过MATLAB仿真显示，带有自适应技术的无线网络，在动态网络编码调度算法作用下，对改进系统性能有着更加重要的现实意义。 |

| Abstract:In recent years, network coding is one of the most importance way of improving communication system throughput。In the multicast network, each node code the data packets of different information flows depend on the various network situation. In this way, the obstruction of every node will reduce and the performance of communication system. The main contribution of this paper mainly reflect in the wireless communication system, we seek the dynamic network coding algorithm to improve the network coding gain and system throughput; this paper also researches the wireless communication system with adaptive technology, which will make the dynamic network coding algorithm much more useful, the sending node or the receiving node, should selects the appropriate adaptive technologies, which does not reduce the network coding gain but improve the spectral efficiency. With the MATLAB simulation and the detailed analysis , wireless communication system adopts adaptive technology and dynamic network coding scheduling algorithm ,which will be more important practical impact on improving the system performance. |
