摘要
文章介绍了Watterson信道模型的特性,并以ITS宽带信道模型为基础,提出了一种改进的窄带短波信道模型,并经过适当的近似与简化,得到了适于计算机仿真的实现结构,改进的窄带短波信道模型考虑了各个传媒模式内的时延扩展,消除了Watterson模型的使用限制,能够仿真更为广泛的短波信道条件。
This paper describes the watterson model. Then, based on the ITS wideband HF channel model, an implementation method suitable for computer simulation is proposed. This new simulation model eliminates the use limitation of Watterson channel model. The delay spread is considered in each propagation mode, and the model could simulate a wide variety of propagation conditions.
