中文摘要：

终端直通（device-to-device,D2D）通信与蜂窝网络共享无线资源的同时,会引起D2D用户、蜂窝用户和基站之间互相干扰,影响通信质量,为此提出一种蜂窝网络中基于网络编码的D2D干扰消除算法。该算法中,D2D发送端将检测到的蜂窝干扰信号与D2D信号进行网络编码,D2D接收端接收到编码信号后,利用干扰重构消除蜂窝干扰信号,达到消除干扰的目的。理论分析与仿真结果表明,该算法在保证D2D用户复用蜂窝用户资源以及提高频谱利用率的同时,可以提高D2D通信系统可达速率和系统吞吐量,进一步降低符号错误概率。

英文摘要：

Considering that the device-to-device （D2D） communication can cause interference among D2D users, cellular users and the base station when sharing wireless resources with cellular network, a D2D interference elimination scheme based on network coding is proposed in this paper. Specifically, the D2D transmitter conducts the cellular interference signals and D2D signals by network coding, and after receiving the encoded signals, the D2D receiver eliminates the cellular interference signals by interferences reconstruction. Performance analysis and simulation results show that, on the premise that the D2D communication system can multiplex cellular user resources and improve the spectrum utilization, the scheme can improve the achievable rate and network throughput of the D2D communication system, and reduce the symbol error probability furthermore.
