摘要
通信感知一体化作为6G的关键技术之一,与大规模MIMO结合有望同时实现高速率通信和高精度感知。首先介绍了通信感知一体化和大规模MIMO的应用场景与需求,然后分析了大规模MIMO通信感知一体化的研究现状,包括波形设计、目标参数估计、感知辅助通信、通信信号处理、通信辅助感知、一体化信号处理和性能权衡等方面,最后展望了大规模MIMO通信感知一体化的未来研究方向,包括超大规模MIMO、无蜂窝大规模MIMO、智能超表面和太赫兹技术。
As one of the key technologies of 6G, integrated sensing and communications(ISAC), combined with massive multiple-input multiple-output(MIMO), is expected to simultaneously provide high-rate communication and high-precision sensing. The application scenarios and requirements of massive MIMO-ISAC are first introduced. Then, the research status of massive MIMO-ISAC is analyzed, including waveform design, target parameter estimation, sensing-assisted communication, communication signal processing, communication-assisted sensing, integrated signal processing, and performance tradeoff. Finally, the future research directions of massive MIMO-ISAC are envisioned, including ultra-massive MIMO, cell-free massive MIMO, reconfigurable intelligent surface, and terahertz technologies.
