摘要
物理层网络编码理论及其应用是当前通信网络领域研究的热点,但是真实场景下的实验平台建设还很少见。文通过USRP+PC软件无线电平台在无线双向中继网络场景下,实现了物理层网络编码视频传输的功能。仿真结果表明,应用网络编码的视频传输和传统的方式相比,可以有效地提高视频的传输质量和效率。
Theories on Physical-layer Network Coding and its application are a hotspot in current research.However,the real situations of experimental platform construction is still very rare.This paper realized the function of the physical layer network coding video transmission by using the USRP ＋ PC software radio platform in wireless two-way relay network scenario.According to the simulation result,application of network coding of video transmission compared with the traditional way,can effectively improve the quality of video transmission and efficiency.
