摘要
首先介绍了短波信道建模的发展历程及其经典的窄、宽带模型,研究了一种宽带短波信道的建模方法,同时研究了其噪声和干扰模型并进行了简化。在模型仿真中分别对其两种多普勒扩展形式进行了仿真和比较,搭建了中纬度1500km路径长F1层宽带短波信道散射模型和噪声干扰模型,最后通过仿真结果与实测数据比较,验证了该模型的合理性。
The development of high frequency channel and its classical narrowband and wideband models are firstly introduced. Then, a modeling method of wideband high frequency channel and its noise and interference is studied. The simulation and comparison of two Doppler spread forms about channel propagating characteristics are given, and an appropriate WBHF scattering model of F1 layer at the elevation of 1500km in midlatitude area is bulit. Finally the rationality of this model is proved by comparing simulation data with measured data.
