| 摘 要： | 研究了频率非选择性瑞利衰落信道中,基于网络编码的双向中继系统的中断性能问题。基于放大重传(Amplify-and-Forward,AF)和联合解码重传(Joint Decode-and-Forward,JDF)机制,在瑞利衰落信道环境下,通过理论分析得出一般情况下的节点和系统中断概率解析式。在此基础上完成了数值仿真实验,结果表明在小信噪比情况下,JDF的中断性能优于AF系统;在大信噪比情况下,AF的中继性能将超过JDF系统的中断性能;随着信噪比以及信道不对称度的增加,AF和JDF系统的中断性能将趋于相同。此外,研究还发现,当速率大于0.5 bit/s.Hz时,JDF系统的中断性能急剧下降。 |

| Abstract: | The outage performance of network coding based the two-way relaying system was investigated.The expressions of the outage probability for the Amplify-and-Forward(AF) and Joint Decode-and-Forward(JDF) based two-way relaying systems were derived in frequency-nonselective Rayleigh fading channels.Numerical simulation experiments were conducted,and the outage performance of the introduced two schemes were compared.The results show that the outage performance of the JDF based system is better than the AF based o... |
