为了提高5G系统的频谱效率，满足移动业务流量增长的需求，本文对具有高网络吞吐量和频谱利用率的双向中继系统进行深入研究，从去噪转发的双向中继系统（2P-DNF-TWR）的模型建立入手，分析了该系统中继和源节点解码的误比特率，并对2P-DNF-TWR系统、解码转发系统和去噪转发系统的误比特率进行了仿真对比，实际仿真结果表明，随着信噪比的增大，去噪转发的双向中继系统的性能均优于2P-DNF-TWR系统和解码转发系统。
為瞭提高5G繫統的頻譜效率，滿足移動業務流量增長的需求，本文對具有高網絡吞吐量和頻譜利用率的雙嚮中繼繫統進行深入研究，從去譟轉髮的雙嚮中繼繫統（2P-DNF-TWR）的模型建立入手，分析瞭該繫統中繼和源節點解碼的誤比特率，併對2P-DNF-TWR繫統、解碼轉髮繫統和去譟轉髮繫統的誤比特率進行瞭倣真對比，實際倣真結果錶明，隨著信譟比的增大，去譟轉髮的雙嚮中繼繫統的性能均優于2P-DNF-TWR繫統和解碼轉髮繫統。

In order to improve the spectral efficiency 5G system,and meet the requirement of the increase in service traffic. This paper makes an intensive study of the two-way relay system which has higher throughput and spectrum efficiency, we still focus on the model-build of two-way denoise-and-forward relaying system and use theoretical and simulative method to analyze the relay and the source node's error bit rate of 2P-DNF-TWR system, decode-and-forward system and denoise-and-forward system. Further numerical result indicates that denoise-and-forward relaying system has the best performance when compared with other two-way relay systems.
