| 中文摘要: |
| 无人机(unmanned air vehicle，UAV)可以作为无线通信系统的放大转发(amplify and forward，AF)中继。为提高无人机辅助中继的通信系统性能，本文考虑了一种配备混合精度模数转换器(analog-to-digital converters，ADCs)的全双工(full duplex，FD)大规模多输入多输出(multiple-input multiple-output，MIMO)的非正交多址接入(non-orthogonal multiple access，NOMA)传输方案，该方案中无人机在悬停状态下为地面用户提供服务。本文采用了最大比合并/最大比传输（maximum ratio combining/maximum ratio transmission，MRC/MRT）方案，并考虑非完美串行干扰消除(successive interference cancellation，SIC)等非理想条件的影响，以系统的频谱效率(spectral efficiency，SE)和能量效率(energy efficiency，EE)为指标对系统性能进行研究和分析。仿真结果表明，系统的性能与中继天线数、用户发射功率、量化比特数等参数有关，同时也证明了混合精度量化系统的优势。 |

| Unmanned aerial vehicle (UAV) can be used as amplify-and-forward (AF) relay in wireless communications systems. To improve the performance of UAV communication, a full-duplex (FD) massive multiple-input multiple-output (MIMO) non-orthogonal multiple access (NOMA) transmission scheme with mixed-resolution analog-to-digital converters(ADCs) is proposed, and UAV provides services to ground users in a hovering state. In this paper, maximum ratio combining/maximum ratio transmission (MRC/MRT) is adopted and the influence such as imperfect successive interference cancellation(SIC) is considered, the performance of the model is investigated and analyzed with the spectral efficiency (SE) and energy efficiency (EE). The simulation results show that the performance of the system is related to the number of antennas, the transmitted power of users, and the quantization bits. In addition, the advantages of systems equipping with mixed-resolution ADC are also demonstrated. |
