Matlab 求声音信号的包络的源代码 使用方法见说明(Matlab for the sound signal envelope of the source code)

mil为设计程序，需要给定设计点的飞行环境状态，以及该点处的参数，需要环境状态文件和螺旋桨设计状态文件，按照手册中说明的格式输入， qprop为电机、螺旋桨组合的分析程序，需要给出电机、螺旋桨以及飞行环境参数文件，按照手册中说明的格式输入，(qprop)

此为模式识别中Parzen窗法估计概率密度函数。 全部程序流程如下： 1、读取FAMALE.TXT文件把身高或体重给数组，并求x1的样本数N1和窗宽、体宽； 2、读取MALE.TXT文件把身高或体重给数组，并求x2的样本数N2和窗宽、体宽； 3、读取Test2.txt文件把对应的身高或体重给数组A并求A的样本数M； 4、利用Parzen窗法估计概率密度函数判别男女性别； 5、对本判别的错误率进行统计。 (This is the pattern recognition Parzen window method to estimate the probability density function . All program flow is as follows : 1 , read FAMALE.TXT file to height or weight to the array, and find the number of samples x1 N1 and window width , body width 2 , read MALE.TXT file to height or weight to the array, and find the number of samples x2 N2 and window width , body width 3 , read Test2.txt file to the corresponding height or weight requirements for the array A and A is the number of samples M 4 , the use of Parzen window method to estimate the probability density function of gender discrimination 5 , determine the error rate of the statistics . )

THIS is the program for a law companding...

2ASK信号的正交解调，包括2ASK信号的产生，与本地载波混频，低通滤波，求包络，恢复出原始信号等(the demodulation of 2ASK)

说明：  PSO的matlab工具箱 群体智能算法：对求解连续函数的极值问题上比GA好用(PSO' s intelligent algorithm matlab toolbox groups: continuous function of solving the issue of the extreme ease of use than GA)

这是2009年huang在EMD基础上改进的算法EEMD的matlab代码！(This is the huang in 2009 based on the improved EMD algorithm EEMD matlab code!)

频谱分析和滤波器设计 ppt文件 MATLAB表述的信号和系统， 用MATLAB与信号流图求系统 频谱分析 离散频谱与连续频谱的转换(Spectrum analysis and filter design ppt file MATLAB expression signals and systems using MATLAB and signal flow diagram for the system spectral analysis of discrete spectrum and continuous spectrum conversion)

说明：  迭代法求解线性方程组，可以运用数值计算方法中的雅克比迭代法求解线性方程组(diadaifa)

添加高斯白噪声子程序 内容虽然很简单，但是很有用哦(Add white Gaussian noise subroutine)
