一种新的莱斯衰落信道仿真模型

A novel simulation models for rice fading channels

一种新的确定型瑞利仿真模型是对MEDS仿真模型中的离散多普勒频率进行改进,通过引入仿真次数因子,克服现有衰落信道仿真模型不能同时满足各态历经特性和平稳特性,以及仿真效率低的缺陷,并在此基础上建立一新的莱斯衰落信道仿真模型。经实验仿真分析得出,新的莱斯衰落信道仿真模型的一阶和二阶统计特性与理想参考模型统计特性相吻合。

A new deterministic Rayleigh simulation model is given. The new simulation model improves the discrete Doppler frequency in the MEDS simulation model by introduced simulation number factor. The new model can overcome the disadvantage that the existing wireless channel simulation models can not be satisfied with ergodic and stationary and low efficiency of simulation. Based on above analysis a new Rice fading channel simulation models is presented. The simulation results show that the first and second order statistical property of the new Rice fading channel simulation model match the ideal reference model.
