摘要
论述了基于LMS算法的自适应噪声抵消器和自适应谱线增强器的工作原理及改进的算法,并将自适应噪声抵消器和自适应谱线增强器合并为一个滤波器应用于电参数测量系统中,仿真实验证明这种滤波器去除噪声的性能较佳。
The theory of adaptive noise canceler and adaptive line enhancement based on LMS algorithm and the improved algorithm are discussed. The filter of the incorporation of the adaptive noise canceler and the adaptive line enhancemen is applied to the system of electricity measure. Emulation proves that the performance of denoising of this filter is excellent.
