介绍了传统线谱增强器(ALE)结构,分析了ALE的工作原理。ALE线谱增强的原因是降低了基本

输入和参考输入中的噪声相关性,由于对参考输入的权系数调整无法对噪声进行合理估计,正弦信号得到增强。

-Introduced the traditional linear spectrum enhancer (ALE) structure, an analysis of the working principle of ALE. ALE-ray spectrum is due to enhance the basic input and reduces the noise reference input relevance, because of the reference input to adjust the weight coefficients of the noise can not be reasonably estimated, enhanced sinusoidal signal.
