Performance Analysis of a Cooperative Network Coding Technique Based on Space-Time Code

  • 摘要: 该文提出了一种基于空时码的协作网络编码技术(Cooperative Network Coding based on Space-Time code,ST-CNC),该技术将协作分集技术和网络编码技术有机结合,能够克服无线信道衰落,提高系统资源利用率和网络吞吐。推导了采用ST-CNC的两跳链状网络中端到端信息交换的误比特率,分析了该技术带来的分集增益和网络编码增益。结果表明:相对于传统的多跳链路的数据交互策略,该技术能够带来明显的性能增益。最后通过仿真验证了分析结果的正确性。
