摘要
在蜂窝网络中,部署了一个设备间(D2D)双向中继网络.每个D2D双向中继节点配备有两根收发天线,分别同时与基站和D2D接收端进行通信.在假设D2D双向中继采用放大转发模式条件下,提出了优化D2D双向中继网络的功率分配方案.仿真结果显示:所提方案的D2D双向中继网络的吞吐量在理想信道下,较随机功率分配和传统通信方式分别提升7%和12%.
In this paper,we assume that a device-to-device （ D2D） bid irection al relay network is deployed in a cellular network. Each D2D two-way relay is equipped with two transmit antennas, which are respectively carried out at the same time with base sta-tion and receiver. Under the assumption that D2D two-way relay adjust power transmission ampl ification,we propose a power al lo-cation scheme of the two-way relay network. The simulation results show that the scheme proposed can obtain larger two-way relay network throughput than the random power allocation and the traditional communication methods.
