Embodiment Construction
[0039] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0040] see figure 1 shown, figure 1 It is a scene diagram of vehicle communication under the cellular vehicle networking in dense urban areas adopted by the present invention. In the example of the present invention, a transmission scenario including two communication modes of V2I downlink and V2V sidelink is considered. In downlink V2I communication, NOMA technology is introduced to increase the number of devices connected to the network, while V2V sideline direct communication reduces the burden on base stations and has lower end-to-end transmission delay. The urban roads are in the shape of a Manhattan grid, and the vehicle distribution follows a one-dimensional Poisson point distribution model. The wireless channel model of the user consists of slow fading and fast fading consisting of path loss, shadow fading. NOMA users adopt the...
