PSK8 demodulator with symbol, phase synchronozation. Model was writed in Simulink.

对四分量的信号进行时频处理，得到小波尺度图、平滑伪wigner图、WVD图。有利于对信号进行很好的分析。(Four components of the signal time- frequency to give Scalogram, smoothed pseudo wigner diagram, WVD FIG. Conducive to good analysis of the signal.)

该模型实在simulink下建立的燃料电池氢气输出模型，可以借鉴或者直接使用(fuel cell H2 model )

手把手教你如何用matlab调用系统程序,并自动控制电脑定时关机(Taught you how to use matlab call system procedures, and automatic computer shutdown timer)

该程序完成的是通过使用所提供的链码（一种方向码）来画出链码所表示的轮廓。所画轮廓在原图上是黑色的线。(the code is used for draw the outline of the region of interest which is show by the chaincode)

2. 设 是窄带信号，定义 是在 区间上均匀分布的随机相位。 是寬带信号，它是一个零均值、方差为1的白噪音信号e(n)激励一个线性滤波器而产生，其差分方程为 。 1） 计算 和 各自的自相关函数，并画出其函数图形。根据此选择合适的延时，以实现谱线增强。 2） 产生一个 序列。选择合适的 值。让 通过谱线增强器。画出输出信号 和误差信号e(n)的波形，并分别与 和 比较。 (Computer Experiments: 1. Consider an AR process x(n) defined by the difference equation where v(n) is an additive white noise of zero mean and variance .The AR parameters and are both real valued: a) Calculate the noise variance such that the AR process x(n) has unit variance .Hence , generate different realization of the process x (n). b) Given the input x (n), an LMS filter of length M = 2 is used to estimate the unknown AR parameters and . The step size is assigned the value 0.05. Compute and plot the ensemble average curve of and by averaging the value of parameters and over an ensemble of 100 different realization of the filter. Calculate the time constant according to the experiment results and compare with the corresponded theoretical value. c) For one realization of the LMS filter, compute the prediction error And the two tap-weight errors and Using power spectral plots of , show that)
