Simulation Analysis Of Radio Wave Propagation Characteristic Based On FEKO

At present, with the full deployment of 4G communication network, the flourish of mobile internet and the putting forward of 5G communication, wireless communication is playing an increasingly important role in people’s life. In wireless communication system, the ability of the communication equipment to combat the fading channel determines the quality of the communication system. In order to improve the ability of communication system to combat the channel fading, it is necessary to master the propagation characteristics of radio wave in different communication scenarios. This is the basis for the design, evaluation and selection of all wireless communication systems. Therefore, the radio wave propagation has been one of the hot spot problems in wireless communication. The work of this paper is carried out under such background and condition.The main work of this thesis is to study the propagation characteristics of radio wave in different scenarios by simulation software FEKO. Simulation is a means to study the characteristics of the propagation of radio wave, mastering the propagation characteristics of the radio wave is the basic purpose.The main contents of this paper include:(1) A simulation method for radio wave propagation based on FEKC is researched, providing a new way and thinking of radio wave propagation research.(2) For a V2V scenario, getting path loss of wave propagation by FEKO simulation is proposed, and the simulation results are compared with the measurement results. The experimental results show that the path loss is smaller than the actual measurement results through the FEKO simulation, which is caused by the simplification of the simulation model.(3) For indoor corridor scenario, the path loss model is analyzed, the relationship between path loss and frequency、antenna position、corridor material and antenna height is given, meanwhile, a comparison of path loss exponent between LOS and NLOS situation of indoor corridor is also analyzed.(4) For indoor corridor scenario, the relationship of delay property and corridor material、frequency is analyzed. Through simulation experiments, it is found that multipath delay is closely related to the structure of the corridor scenario, but there is no significant relationship between the material and the frequency band of the corridor.Exploring the propagation characteristics of radio wave in different communication scenarios by means of simulation offers data support for accurate channel modeling.
