Embodiment
[0049] This embodiment includes the following steps:
[0050] The first step is the resource modeling based on the spectrum geographic database, which is specifically as follows: In this embodiment, the following settings are made: the coverage area of the car networking base station is 4000m, and the base station is located at 2000m. There are 3 blank channel resources, 509MHz, 575MHz and 635MHz, and the available ranges are [500,3500],[1000,3000],[1500,2500]. The available bandwidth of each channel is 5.33MHz, including 35 sub-channels (that is, the sub-channel width is 5.33 / 35MHz), the spatial granularity is set to 1m, the interval length of different speeds is set to 500m, and the signal-to-noise ratio in each interval is used. The minimum value within indicates. There are 6 vehicles in total. The current locations are 800, 1200, 1600, 2400, 2800, 3200, and the data requirements are 10, 20, 30, 30, 20, and 10 respectively. The unit is Mbit and the speed is 60km / h. Through...
