3.5GHz车联网信道测量与仿真对比分析
Contrastive analysis of internet of vehicles on channel measurement and simulation at 3.5 GHz
摘要
Abstract
In this paper,measurement and analysis are carried out for 3.5 GHz in the 5th generation (5G)mobile communication test frequency band.The self-developed frequency domain channel sounding system is used to measure the 3.5 GHz channel in the vehicular network scenario.Moreover,the same channel data is generated by the self-developed ray-tracing simulator.The calibrated geometric model and material library are used to simulate the measured scenario and compare with the received power of the measured result.Finally,the path loss curves of the measured and simulated results are fitted by the logarithmic distance path loss model.The results show that the relative error of path loss factor and standard deviation of the simulated scene are less than 7 %,which verifies the effectiveness and accuracy of the raytracing simulator in channel simulation.Both the path loss exponent and shadowing factor,which are studied in this paper,will be useful for the frequency band selection and network deployment of the 5G vehicular networks at frequencies lower than 6 GHz.关键词
