High Frequency Channel Modeling And Simulation In Next Generation Mobile Communication Systems

As the next generation communication network is more demanding in terms of channel capacity and spectrum efficiency, it needs more spectrum bandwidth support. Therefore, in the development of next generation communication technology, channel modeling in high frequency band becomes an important research direction. How to accurately characterize the channel becomes a challenge for organizations and research institutions because of the characteristics of wireless channel which may be difficult to be reflected in low frequency conditions under high frequency conditions. The paper carries on the channel modeling research, and the main work is as follows:(1) In this paper, the modeling and calibration of high frequency channel are studied and simulated. The characteristics of wireless channel under high frequency are analyzed, which provides a theoretical basis for the establishment of high frequency channel model.(2) The modeling method of HF channel model and the simulation calibration and analysis of the model are discussed. The 3D MIMO channel model is extended to the high frequency band using the modeling method based on geometric statistics, and the modeling steps of the high frequency channel are given.(3) In order to ensure the accuracy of the channel model, the high frequency channel model is simulated and the simulation results are calibrated from the large-scale parameter, the small-scale parameter and the additional high-frequency characteristic parameter to ensure the accuracy of the simulation results.(4) The simulation results of the high frequency channel are analyzed qualitatively. The performance and some parameters of the high frequency channel are briefly described.In this paper, channel modeling is an abstract description of the wireless communication environment. Using a series of parameters and modeling steps to describe the physical characteristics of the transmission environment, it can accurately depict the transmission mechanism of the wireless signal is an important means to evaluate the performance of wireless technology.
