摘要:

受限于设备条件和计算机网络层级,传统研究将传感设备端的数据感知、服务器端的数据计算和两端之间的数据通信视为相互独立的环节,缺乏全局考虑,严重阻碍了数据处理的效率。为了提高数据感知和传输效率,通信感知融合技术致力于设计同时支持雷达感知和数据通信的复用信号。为了提高数据传输与计算效率,空中计算旨在利用信号在无线多址信道传输过程中的波形叠加性质,在数据传输的同时直接进行计算。为了实现高效准确的数据处理,可以利用通信感知融合技术中的复用信号和空中计算技术中的波形叠加属性,实现基于空中计算架构的通信感知计算一体化,并通过对波束赋形器等信号处理环节进行设计,以降低信道噪声和信号干扰,从而提升数据在通信感知计算过程中的准确度。该技术可应用在目标探测、车联网、边缘智能等多个领域。实验结果表明,相比于传统方案,基于空中计算架构的通信感知计算一体化可以显著提升数据处理的效率和准确度。

Abstract:

Limited by equipment conditions and computer network hierarchy,traditional researches treat data sensing,communication,and computation as independent processes,which lack global consideration and seriously hinder the efficiency of data processing.To improve the efficiencies of data sensing and transmission,the sensing-communication fusion is proposed to design dual-functional signals for supporting both radar sensing and data communication.To improve the efficiencies of data communication and computation,over-the-air computing aims to exploit the waveform superposition property of signals in the multiple access channel to enable data computation during transmission.In order to achieve efficient data processing,the dual-functional signals in sensing-communication fusion and the waveform superposition property in over-the-air computing are utilized to realize the integrated sensing,communication,and computation over the air.The corresponding beamformers are designed to reduce channel noise and signal interference,so as to improve the accuracies of sensing,communication,and computation.This technology can be applied in various fields such as target detection,vehicle networking,and edge intelligence.Experimental results show that the technology can significantly improve the efficiency and accuracy of data processing in comparison with the traditional schemes.

Key words: integrated sensing, communication, and computation, sensing-communication fusion, over-the-aircomputingarchitecture
