用matlab软件对HSUPA系统进行仿真，主要是调度算法之类(HSUPA systems using matlab software to simulate, mainly scheduling algorithm )

说明：  对多机电力系统进行小干扰稳定分析 可以计算特征值，特征向量(Of multi-machine power system small signal stability analysis can calculate the eigenvalue, eigenvector)

通信原理仿真 码型反变换的仿真实现 Ⅰ、基本任务：由抽样判决后的AMI码型和CMI码型数字序列恢复出原始的PCM脉冲编码信号。 主要步骤和要求： （1）由抽样判决后的AMI码型数字序列恢复出原始的PCM脉冲编码信号（0、1信号）。要求抽样判决后的AMI码型数字序列可以是数字型也可以是字符型；要求画出码型反变换前后的波形图。 （2）由抽样判决后的CMI码型数字序列恢复出原始的PCM脉冲编码信号。要求抽样判决后的CMI码型数字序列可以是数字型也可以是字符型；要求画出码型反变换前后的波形图。 Ⅱ、选做任务：由抽样判决后的HDB3码型数字序列恢复出原始的PCM脉冲编码信号。 主要步骤和要求： 由抽样判决后的HDB3码型数字序列恢复出原始的PCM脉冲编码信号（0、1信号）。要求抽样判决后的HDB3码型数字序列可以是数字型也可以是字符型；要求画出码型反变换前后的波形图。 (Communication theory simulation Fifth problem, Pattern Simulation of inverse transform Ⅰ, basic tasks: decision by the sampling pattern after AMI and CMI pattern sequence to recover the original digital PCM pulse code signal. Main steps and requirements: (1) post-judgment by the AMI code sample digital sequence to restore the original PCM pulse code signal (signal 0,1). AMI requires post-judgment sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform. (2) post-judgment by the CMI sampling digital code sequence to restore the original PCM pulse code signal. Requirements of post-judgment CMI sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform. Ⅱ, choose to do the task: the post-judgment by the sample type HDB3 code sequence to recover the original digital PCM pulse code signal. Main steps and requirements: Pos)

此文件夹包含antongdaoquwu.m主程序文件和antongdao.m子程序文件，都是自己写的，用matlab语言写成，用于图像去雾，可将一幅有雾的模糊图像转化成去雾后的清晰图像，缺点是效率不高，处理一张图片需要1秒左右，不能用于工业化，可以将关键部分改写成C代码提升速度。(This folder contains the main program file and antongdao.m antongdaoquwu.m subroutine files, are their own written language written with matlab for image defogging, there may be a blurred image is converted to go after the fog fog clear image, the disadvantage is not efficient, the process takes about one second a picture can not be used for industrial, it can be a key part of the C code rewritten to increase speed.)

说明：  迭代法 最简单的方法求取一个阈值 用来分割图像(Iteration threshold 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(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 )
