摘　　要：针对浓雾对移动通信信道的特殊影响,综合考虑多径效应、阴影效应、吸收衰减对信道的负面影响,以阴影效应下包含直射路径的多径效应为依据,从数学角度推导了符合浓雾天气下信道特性的信道统计模型并给出了统计模型的数学实现方法.最后以ITU关于下一代(5G)移动通信的相关数据对通信模型的性能予以仿真,通过比较实测信道和所提信道模型的电平交叉率和平均衰落时间两个性能参数,验证了信道模型可以有效反映信道的实际特性,对浓雾天气下的移动通信相关技术研究有一定的适用价值.In order to solve the special influence of dense fog on mobile communication channel,the negative effects of multipath effect,shadow effect and absorption attenuation on channel are considered comprehensively.Firstly,the channel statistical model which conforms to the channel characteristics of dense fog weather is established,and then the mathematical implementation method of statistical model is given.Finally,the performance of the communication model is simulated with the measured parameters.It is verified that the channel model can effectively reflect the actual characteristics of the channel by comparing the two performance parameters of the level crossing rate and the average duration of fades in the measured channel and the channel model.
