| 摘 要： | 针对短波突发通信的特点,对几种常用的自适应均衡算法进行了研究,并运用MATLAB工具对算法的性能进行了仿真比较。结果表明:LMS算法计算简单,收敛速度较慢;RLS算法计算量很大,收敛速度快,但对累积舍入误差敏感;平方根Kalman算法计算量较大,收敛速度快,对累积舍入误差不敏感。

| Abstract: | The paper researched on several common algorithms of adaptive equalization based on the characters of HF burst-mode communication,and the performance of algorithms were simulated and compared by MATLAB.The result showed that LMS algorithm is simple but the speed of convergence is slower;the calculation of RLS algorithm is complex,speed of convergence is fast,but it is sensitive for the cumulate rounding errors;the calculation of Square Root Kalman algorithm is simpler than RLS algorithm,speed of convergence is fast,and is not sensitive to the cumulate rounding errors. |

| Keywords: | HF instantaneous communication adaptive equalization LMS algorithm RLS algorithm square root Kalman algorithm |
