Embodiment Construction
[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0032] The basic principle of mobile channel detection and perception is as follows: figure 1 As shown, the figure is a schematic diagram of the V2V communication scene. Through the distributed array antenna detection method, the airspace channel characteristics can be directly obtained, which can effectively improve the spatial resolution of the mobile channel and provide a guarantee for the subsequent real-time channel multi-dimensional analysis. The circular antenna array is realized by using the spatial combination of beam scanning antennas. The switching of the antenna radiation pattern adopts the DC feed control method, and the switching between the antennas is realized by a high-speed microwave switching switch. The method can directly ob...

The invention discloses a low complexity modeling based multidimensional channel perception system of the internet of vehicles. According to the system, multidimensional scan and detection for time-space domain can be achieved by adopting a distributed mobile channel detection method and through a distributed stealth micro-strip perception antenna array arranged at the periphery of a vehicle body; multidimensional time-varying parameters of a mobile channel can be obtained in real time by adopting a low complexity modeling algorithm based on discrete ellipsoid sequence (DPS) subspace and analyzing channel propagation characteristics during a movement of a vehicle; and a channel change track of a moving vehicle can be accurately estimated, changes of environments surrounding the vehicle can be analyzed, and multidimensional perception of the mobile channel of the internet of vehicles can be achieved. Limitations of a conventional system which perceives a vehicle based on a plurality of sensors are broken according to the low complexity modeling based multidimensional channel perception system of the internet of vehicles, advanced distributed mobile channel detection and a low complexity modeling technology are adopted, and perception of environments surrounding a vehicle in application of the internet of vehicles is improved.
