    3D channel modeling and space-time correlation analysis for V2V communications by Wenbo ZENG, Yigang HE, Bing LI, Guolong SHI, Feng ZHAO

    Published 2019-06-01
    “…To match complex wireless propagation scenarios,an improved 3D geometry-based stochastic model was proposed for vehicle to vehicle (V2V) communications channel.The exact relationship between the azimuth angle and elevation angle was taken into account and the corresponding space–time correlation function and space–Doppler power spectral density were derived,and the influence of important factors was analyzed.The observations and conclusions show that correlation characteristics is closely related to distribution of the scatterers and the angle of the antenna array under the non-isotropic scattering environment and is affected by the elevation angle of the antenna array under the isotropic scattering environment.And the space-time correlation characteristics in high vehicular traffic density is significantly lower than that in low vehicular traffic density.The corresponding simulation model is also derived by using a reasonable parameter calculation method.The simulation results validate the rationality of proposed model.It greatly improves analysis and simulation efficiency of V2V MIMO system.…”

    Research status and development trend of blockchain in cellular mobile communication system by ·iping ZUO, Shi JIN, Shengli ZHANG

    Published 2019-09-01
    “…The blockchain is essentially a distributed database that can be safely updated without the need for third-party intermediaries.The blockchain technology is introduced into the 6G cellular mobile communication system to ensure the privacy of users,reduce the cost of resource allocation and communication services,and support different distributed applications.In order to realize the organic combination of mobile communication and blockchain technology,it is predicted to be one of the key technologies of 6G cellular mobile communication.From the blockchain combined with internet of things (IoT),edge computing,spectrum allocation,interference management,a detailed introduction was introduced,and the latest research progress of international academic circles in this direction was expounded in recent years,and on this basis,the development trend of blockchain technology in 6G cellular mobile communication was further prospected.…”
