| 摘 要： | 无线移动信道由于电波在移动信道中时域与空域上传输时,有很大的随机波动与起伏的特点,控制与测量一般难以把握,通过数值计算与路径损耗建立模型与仿真,能够较好地预知信道特性。根据无线移动信道模型特征建立无线移动信道模型,然后对自由空间模型、经验模型Okumura-Hata模型、COST-231 Hata模型以及COST231-WI模型进行了建模与仿真,并将对仿真结果进行了分析,为无线移动通讯信道传播模型选择提供参考。

| Abstract: | The transmission of electric wave at time domain and space domain in the wireless mobile channel has the characteristics of high random fluctuation,so the control and measurement are very difficult.The modeling and simulation based on numerical calculation and path loss can predict the channel characteristics.First of all,the wireless mobile channel model is established according to the characteristics of wireless mobile channel model,and then the modeling and simulation are implemented for free space model,empirical model Okumura-Hata model,COST-231 Hata model and COST231-WI model.The simulation results are analyzed,which provides reference for wireless mobile communication channel propagation model selection. |
