Abstract

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
