摘　　要：针对远距离通信实验开展不便的问题,基于LVC仿真体系的思想,提出使用信道模拟器实现室内测量环境。针对超短波无线链路损耗计算问题,使用Matlab对Okumura-Hata、COST-231 Hata、COST-231WI模型进行仿真,仿真结果给出超短波在城市、郊区、农村开阔地等情况传播损耗,分析超短波在不同场景中传播损耗特性,对照WRAP软件的无线链路计算工具,证实仿真结果的正确。Aiming at the inconvenience of long-distance communication experiments,based on the idea of LVC simulation system,it is proposed to use a channel simulator to realize an indoor measurement environment. Aiming at the problem of calculating the loss of ultrashort wave wireless link,Matlab is used to simulate the Okumura-Hata,COST-231 Hata,and COST-231 WI models. The simulation results show the propagation loss of ultrashort wave in cities,suburbs,and open areas in rural areas. The propagation loss characteristics of ultrashort wave in different scenarios are analyzed. Comparing with the wireless link calculation tool of the WRAP software,the simulation results are verified to be correct.
