Discussion of Vehicular Networking Signal Waveform Design Based on Inte-grated Sensing and Communication
The 6G network can support various applications under the"intelligent connection of everything"with its full coverage of air,space,ground and sea and the integrated application of synaesthesia computing technology.In the application of Internet of Vehicles based on the inte-gration of communication and perception,in order to meet the perception requirements of the target object such as communication and positioning,ranging,and speed measurement,the wireless interface needs to be supported by key air interface technologies such as waveform de-sign and beamforming.Through the study of the signal waveform design scheme of the wire-less air interface in the integrated network system of communication and perception,the charac-teristics of various schemes and their adaptability to the application of Internet of Vehicles are compared and analyzed.In particular,the implementation mode and modulation process of the orthogonal time-frequency air-conditioning scheme that can solve the Doput frequency shift of the perception signal are specifically explored,the peak-average power ratio is analyzed,and the challenges that it may face when applied to the Internet of Vehicles arc discussed.
