| 摘 要： | 针对目前罗兰C接收机用模拟滤波器抑制噪声方面的缺陷,将基于LMS算法(最小均方准则)的自适应谱线增强器应用于抑制罗兰C接收机中噪声,并且与用Remez算法设计的FIR滤波器进行比较。通过仿真得到,自适应谱线增强器比Remez算法设计的FIR滤波器的滤波效果要好得多。

| Abstract: | This paper uses the adaptive spectral-line enhancer based on LMS algorithm to suppress the noise which aims at the limitation of current Loran-C receiver with analog filter and contrasts this technique with an filter designed by Remez algorithm.It is shown by the results of simulation that even the adaptive spectral-line enhancer with less orders has a better effect on noise than the filter designed by Remez algorithm. |
