摘　　要：针对物联网市区环境的特点,提出了一种改进的Rayleigh衰落信道模型.以Clarke模型为基础,合并相邻路径入射角度,分离其初始相位,并对相关统计特性进行了推导研究.仿真结果表明该模型在降低约一半计算量的同时,基本符合Clarke理想特性,保证了良好的独立性.the Internet of An improved Rayleigh fading channel model is presented in an urban environment of Things （IOT）. Based on the Clarke model, the proposed method combines the adjacent paths＂ angles of arrival, and separates the initial phases. The related statistical properties are also de- rived. Simulation results show that this improved model is basically in line with Clarke ideal character- istics, while reducing about half of the computation, and has a good performance of independence.
