| 摘 要： | 针对短波信道不可逆性、多径以及衰落等特点,提出了一种纯软件的短波信道仿真算法。该算法以Watterson模型为基础,具有简单易行、可移植性强、全数字化等特点,并可实时嵌入到调制解调器中,使该调解器兼有信道模拟器的功能,具有很重要的实际意义。仿真和数字信号处理器的实现验证了该算法的有效性。

| Abstract: | A software high frequency (HF) channel simulation algorithm is presented aiming at the characteristics of HF channel which has unrepeatability, multipath and fading. This algorithm is more simpler, removable and digital than other algorithms. At the same time, it can be superimposed into modem so that the modem can be used as a simulator. It has a important practical significance. Simulation and implementation with DSP verify this algorithm. |
