移动通信过程中由于移动设备所处的环境不同,存在不同的信道衰落,从各种衰落模型的相互关系出发,提出了一种移动无线衰落信道混合应用模型。通过实现瑞利衰落分布和对数正态分布,经线性和非线性变换可以得到Nakagami和Suzuki等分布。对提出的复合衰落模型进行仿真,仿真结果符合理论值。该混合衰落模型设计和仿真方法可以用于指导信道模拟器设计和通信系统仿真。
Due to the different environments of mobile devices in mobile communications, different channel fading exists. Based on the interdependence of various fading models, a hybrid wireless fading channel application model is proposed. By implementing the Rayleigh fading and log-normal distributions, Nakagami and Suzuki distributions can be obtained through linear and nonlinear transformation. The proposed composite fading model is simulated, the simulation results are in line with the theoretical value. This hybrid fading model design and simulation approach can be used to guide channel simulator design and communication system simulation.
