论文摘要
在本文中，我们提出了一个通过波段全复式（FD）无线电启用的集成感应和通信（ISAC）系统，其中配备有混合类似物和数字（A/d）梁形的大量多输入多输出（MIMO）基站通过多个下链链路（DL）的用户以及同时估计（同时）的方向（DL），并且（同时）的方向（dl），以及（同时），并且（doce）的方向（dlape tocrape synement）以及同步（dove）的方向（dl），并同时使用方向（doce）。目标随机分布在其覆盖区域内。利用最近降低的复杂性FD混合A/D光束形成结构，我们设计了一个关节雷达目标跟踪和DL数据传输协议。提出了针对大规模A/D光束器联合设计的优化框架和自我干扰（SI）取消单元，其双重目标是提高雷达跟踪精度和DL通信性能的双重目标。我们使用5G NR宽带波形在毫米波频率下以毫米波频率进行了仿真结果，展示了所提出的系统的雷达目标跟踪性能的准确性，该系统与基准方案相比，该系统同时提供了增加的总和速率。
In this paper, we present an Integrated Sensing and Communications (ISAC) system enabled by in-band Full Duplex (FD) radios, where a massive Multiple-Input Multiple-Output (MIMO) base station equipped with hybrid Analog and Digital (A/D) beamformers is communicating with multiple DownLink (DL) users, and simultaneously estimates via the same signaling waveforms the Direction of Arrival (DoA) as well as the range of radar targets randomly distributed within its coverage area. Capitalizing on a recent reduced-complexity FD hybrid A/D beamforming architecture, we devise a joint radar target tracking and DL data transmission protocol. An optimization framework for the joint design of the massive A/D beamformers and the Self-Interference (SI) cancellation unit, with the dual objective of maximizing the radar tracking accuracy and DL communication performance, is presented. Our simulation results at millimeter wave frequencies using 5G NR wideband waveforms, showcase the accuracy of the radar target tracking performance of the proposed system, which simultaneously offers increased sum rate compared with benchmark schemes.
