| 摘 要： | 分析了模拟网络编码双向中继窃听信道可达安全速率特性的影响因素.建立了存在一个窃听者的窃听信道模型,并推导了可达安全速率的表达式.通过对特定场景进行数值仿真和分析,结果表明:当窃听者位于某些范围内时,存在可达安全速率为零的情况;通过增大窃听者和被窃听节点之间的距离、角度和优化节点功率分配,可以提高模拟网络编码双向中继窃听信道的可达安全速率. |
| 关 键 词： | 窃听信道 双向中继 模拟网络编码 可达安全速率 |

| Abstract: | The factors influencing the achievable secrecy rate of analog network coding over two-way relay wiretap channel are analyzed.A model of wiretap channel with an eavesdropper is established,and the achievable secrecy rate is derived.By numerical simulation and analysis of special scenes,it is concluded that: when eavesdropper locates in some area,the achievable secrecy rate may be 0;by increasing the distance and angle between eavesdropper and the node,or by optimizing the power allocation,the achievable secrecy rate can be enhanced. |
| Keywords: | wiretap channel two-way relay analog network coding achievable secrecy rate |
