摘要:

传感和通信(ISAC)功能的集成作为硬件、功率、频谱和成本高效的解决方案最近获得了显著的研究兴趣。该实验工作的重点是一个双功能的雷达传感和通信框架,其中一个单一的辐射波形,无论是全向或定向,可以实现雷达传感和通信功能。我们研究了一种权衡的方法,可以平衡通信和雷达传感的性能。设计了一个基于正交频分复用(OFDM)的多用户多输入多输出(MIMO)软件无线电(SDR)测试平台,验证了双功能模型。我们进行了空中实验,以研究最佳的权衡因素,以平衡这两个功能的性能。在雷达性能方面,我们测量了我们传输的输出波束图,以检查它们与基于仿真的波束图的相似性。在通信方面,我们从测试平台获得了误比特率(BER)结果,以显示使用双功能波形的通信性能。我们的实验表明,双功能的方法可以实现可比的BER性能与纯通信为基础的解决方案,同时保持良好的雷达波束图。

英文摘要:

The integration of sensing and communication (ISAC) functionalities have recently gained significant research interest as a hardware-, power-, spectrum- and cost- efficient solution. This experimental work focuses on a dual-functional radar sensing and communication framework where a single radiation waveform, either omnidirectional or directional, can realize both radar sensing and communication functions. We study a trade-off approach that can balance the performance of communications and radar sensing. We design an orthogonal frequency division multiplexing (OFDM) based multi-user multiple input multiple output (MIMO) software-defined radio (SDR) testbed to validate the dual-functional model. We carry out over-the-air experiments to investigate the optimal trade-off factor to balance the performance for both functions. On the radar performance, we measure the output beampatterns of our transmission to examine their similarity to simulation based beampatterns. On the communication side, we obtain bit error rate (BER) results from the testbed to show the communication performance using the dual-functional waveform. Our experiment reveals that the dual-functional approach can achieve comparable BER performance with pure communication-based solutions while maintaining fine radar beampatterns simultaneously.
