This program apply downsampling on a speech file.

此代码为本人在做灰色关联度分析时所用的matlab代码，所用实验数据也在，可以直接运行，希望能对其他学习灰色关联度分析的人员有用。(This code is I do gray correlation analysis used matlab code, the experimental data are used, can be run directly, hoping to be useful for other learning gray correlation analysis of staff.)

bpsk加噪和不加噪情况下最佳相干解调的编解码。(The BPSK adding noise and without noise coherent demodulation codec.)

m序列产生源程序，很好用！输入本源多项式，可生成指定长度，指定掩码，指定相位长度的序列(m Serial Generator.)

说明：  近完美重构多相滤波器组实例，包含分析滤波器，综合滤波器，其中原型滤波器系数可调整，以及重构错误的仿真。(Near perfect reconstruction polyphase filter example, contains analysis filters, synthesis filters, which can adjust the prototype filter coefficients, and the reconstruction error is simulated.)

使用matlab 编写用有限元法求解偏微分方程的实例。(Examples of the use of matlab prepared to solve partial differential equations using the finite element method)

This is a general Evolutionary programming program in MAT LAB. In the place of objective objective function, type in your objective function.

说明：  本人自己编写预测算法源程序 DMC 与各位共享(I write your own predictive algorithm to share with you the source DMC)

利用现代谱估计中的AR 模型求取仿真噪声信号和真实噪声信号的模型参数，然后利用这些参数求得信号的功率谱图，通过功率谱图定性地描述主噪声源和次噪声源。在利用信号功率谱图定性描述噪声源后，进一步地利用曲线相似度和曲线关联度定量的识别主噪声源和次噪声源(Use of modern spectral estimation of AR model to strike a realistic simulation of the noise signal and noise model parameters, and then use these parameters obtained by the signal power spectrum, power spectrum qualitatively described by the main noise source and the second noise source. In the use of qualitative description of the noise signal power spectrum of the source, the further use of the correlation curve and the curve of quantitative similarity identification of the main noise source and the second noise source)
