摘　　要：Rician衰落信道是一种重要的小尺度衰落信道。由于多普勒频移为随机值的Rician衰落信道仿真模型不适用于查表法,因此对多普勒频移进行了改进,设计出一种适用于查表法的Rician衰落信道仿真模型。通过理论及仿真分析,获得当谐波数达到100后,该模型在保持统计特性基本不变的情况下可极大地提高仿真速度。The Rician fading channel is an important Small-Scale fading channel. The simulation model with random Doppler frequency can not use the table look-up method. Based on the sum of sinusoids method, a novel Rician fading channel simulation model is presented, which is compactable with the table look-up method. Mathematical derivations are provided. Corresponding simulation results indicated that the model could greatly increase the simulation velocity when the sinusoids achieve 100 while maintaining the statistical performance nearly unchanged.
