摘要

本研究探讨了中继辅助认知无线电(CR)与核能检测(KED)的设备对设备(D2D)通信的性能。D2D用户使用KED技术来感知蜂窝用户(CU)信道，并在发现它空闲时使用相同的技术。D2D通信系统采用多输入多输出(MIMO)和非正交多址(NOMA)技术来减少衰落的不良影响，提高频谱效率。继电器将从D2D源接收到的数据转发到D2D目的地，并且在每个目的地设备上，使用最大比率组合(MRC)技术将接收到的信号组合。将中断概率作为性能度量进行研究。针对所考虑的网络场景，建立了中断概率的分析模型。开发了仿真框架，并对分析框架进行了验证。

Outage Analysis of a D2D Network for MIMO-NOMA-based Downlink Transmission

This study investigates the performance of a relay-assisted cognitive radio (CR) enabled device-to-device (D2D) communication with Kernelized Energy Detection (KED). A D2D user uses KED technique for sensing the cellular user (CU) channel and uses the same while it is found to be idle. The D2D communication system uses multiple-input and multiple-output (MIMO), and non-orthogonal multiple access (NOMA) techniques to reduce the bad impact of fading and improve spectrum efficiency. The relay forwards the data received from a D2D source to a D2D destination and at each destination device, the received signals are combined using the maximal ratio combining (MRC) technique. The outage probability is studied as a performance metric. An analytical model of the outage probability for the considered network scenario is developed. A simulation framework has been developed and validated with the analytical framework.
