自适应线谱增强算法通过自适应技术减弱噪声，并增强有用信号的功率谱。(This demonstration illustrates the application of adaptive filters to signal separation using a structure called an adaptive line enhancer (ALE). In adaptive line enhancement, a measured signal x(n) contains two signals, an unknown signal of interest v(n), and a nearly-periodic noise signal eta(n). The goal is to remove the noise signal the measured signal to obtain the signal of interest)
