本程序能实现任意阶的Zernike多项式的系数模拟和相位屏模拟。(This procedure can be of any order Zernike polynomial coefficient simulation and phase-screen simulation.)

是基于四阶累积量的旋转不变因子ESPRIT算法，在matlab环境下实现(Is based on the cumulative amount of rotation of fourth-order constant factor ESPRIT algorithm in matlab environment to achieve)

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(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 )

对雷达信号实现脉冲压缩处理，并画出图形。 (Achieve pulse compression radar signal processing, and draw graphics.)

非线性信道matlab仿真程序，可以实现色散和非线性效应(nonlinear fiber)

word里包含matlab程序代码与处理效果，从原理上实现了图像的边缘检测，效果理想(matlab code word contains the treatment effect, to achieve image edge detection in principle, the desired effect)

说明：  齐声效应，能模拟几个演奏者同时演奏，但实际只有一个演奏者。(Chorus effect, can simulate several players while playing, but actually only one player.)
