摘要

提出了一种用于集成传感与通信(ISAC)系统的非均匀波束方向图调制(NUBPM)方案,该方案利用波束方向图指标携带附加信息,提高了频谱效率。我们分析了所提出的NUBPM方案的传感性能和频谱效率,这取决于波束模式及其激活概率。此外,为了提高启用nubpm的ISAC系统的性能,我们研究了波束方向图集设计和激活概率优化。仿真结果表明,该方案在保持传感性能不变的情况下,在频谱效率方面明显优于现有的ISAC设计。通过该方案获得的频谱效率也可以用于ISAC系统的通信和传感性能之间的新平衡。

Non-uniform beam pattern modulation for joint sensing and communication in 6G networks
This paper proposes a non-uniform beam pattern modulation (NUBPM) scheme for integrated sensing and communication (ISAC) systems, where the beam pattern indices are adopted to carry additional information, increasing the spectral efficiency. We analyze the sensing performance and spectral efficiency of the proposed NUBPM scheme, which depends on the beam patterns and their activation probabilities. Furthermore, to improve the performance of the NUBPM-enabled ISAC systems, we investigate the beam pattern set design and activation probability optimization. Simulation results show that the proposed scheme considerably outperforms existing ISAC designs in spectral efficiency while keeping the same sensing performance. The gained spectral efficiency through the proposed scheme can also be traded off for novel equilibria between communication and sensing performance for ISAC systems.
