AI 中文摘要
近年来，通感一体化（ISAC）引起了未来蜂窝网络的广泛关注。目前，已有多种工作展示了现有无线通信系统中的感知性能。由于无线电监管的原因，大多数演示基于无源类型。然而，由于商业蜂窝系统中通信协议栈的访问困难，对半协作无源ISAC的蜂窝通信信号评估受到限制。本文利用开源5G框架和软件定义无线电设备开发了一个半协作无源ISAC系统，并通过利用所开发系统实际5G信号的物理层信息进行了实验性能评估。在该系统中，通过5G信号建立通信，并获取和提取物理层信息进行分析。通过在包括同步、ping和数据传输在内的多种通信场景下进行实验，验证了系统的性能。收集了不同的物理层信息，并通过多径配置分析了传播特性。实验结果表明，不同的通信场景使用了不同的带宽，并且通过两种不同方法成功检测到了多径。这些结果表明，所开发的系统在更广泛的应用领域中对半协作无源ISAC具有前景。
英文摘要
In recent years, integrated sensing and communication (ISAC) has attracted significant attention towards future cellular networks. Currently, various works have demonstrated sensing performance in existing wireless communication systems. Most of the demonstrations are based on passive type due to the radio regulatory. However, because of the difficulty in access to the communication protocol stacks in commercial cellular systems, the evaluation of the cellular communication signals for semi-cooperative passive ISAC is limited. In this paper, a semi-cooperative passive ISAC system is developed with open-source 5G framework and software-defined radio devices. And the performance is experimentally evaluated by utilizing the physical layer information of actual 5G signals from the developed system. In this system, communication is established with 5G signals and physical layer information are obtained and extracted for analysis. The performance of the system is verified by conducting experiments under several communication scenarios including the synchronization, pinging, and data transmission. Different physical layer information is collected, and the propagation characteristics are analyzed by a multi-path configuration. The experiment results demonstrated that variable bandwidths were utilized for different communication scenarios and the multipath was successfully detected with two different approaches. These results show that the developed system is promising for semi-cooperative passive ISAC in wider application fields
