摘　　要：论文讨论了短波天波信道的特性,建立了CCIR描述的恶劣短波天波信道模型,并且对该模型的特性进行了全面的仿真研究;在此基础上,仿真比较了线性均衡方法两大类算法,即最小均方算法、递归最小二乘算法对该模型的均衡效果,最后进行了性能比较。The characteristic of HF sky-wave channel is discussed in this paper, and then the model of bad HF sky-wave channel de- scribed by CCIR is derived and its performance is researched by comprehensive simulation. On the basis of above work, the simulation compares two algorithms of linear equalization, that is, the effect of least mean square（LMS） and recursive least square（RLS） equalization algo- rithms. Finally, performance comparison is performed.
