HF channel model used to design a modem of 9600 bps in 3khz BW

这一信道模型能够描述由电离层和对流层反射的短波信道，以及建筑物密集的城市环境。12瑞利衰落只适用于从发射机到接收机不存在直射信号（LoS，Line of Sight）的情况，否则应使用莱斯衰落信道作为信道模型-This channel model is able to describe the HF channel reflected by the ionosphere and troposphere, as well as building a dense urban environment.

这是一个经典的信道模型matlab程序，多径衰落，对于短波通信的仿真具有很好的参考价值-This is a classic channel model matlab program, multipath fading, for the simulation of HF communication has a good reference value
