论文 matlab 基于小波变换的信号去噪方法研究(Paper matlab signal denoising based on wavelet transform method)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

一种改进的速度估计算法与原算法的对比，直接运行english.m即可得到结果(compared an improved speed estimation algorithm with the original algorithm, the results can be obtained directly from run english.m)

小波分析是目前数学中一个迅速发展的新领网域，它同时具有理论深刻和应用十分广泛的双重意义。信号处理的目的就是：准确的分析、诊断、编码压缩和量化、快速传递或存储、精确地重构（或恢复）。(Wavelet analysis is a rapidly developing new collar domain in mathematics, which has both theoretical significance and profound and extensive application. The purpose of signal processing is: accurate rapid analysis, diagnosis, coding and quantization, transmission or storage, accurate reconstruction (or recovery).)
