求解出一段语音的短时平均幅度差函数AMDF,并绘制其波形图。(A speech to solve the short-term average range difference AMDF function, and draw the waveform figure.)

神经网络的使用方法，希望对大家有用，适合有基础的学生自己研究(Use of neural networks, we want to be useful for students who have their own research foundation)

BPSK modulation with Hard decision type of coding.

说明：  修正BBO晶体折射率色散公式中错误的系数 ，完成βBBO晶体Ⅱ类匹配的SPDC（共线情况）并计算相位匹配角。此时的相位匹配角为能 产生纠缠光子对的最小切割角。另附一份参考文献，详细的说明此类实验的步骤与细节。(Correct the wrong coefficient in the refractive index dispersion formula of BBO crystal, complete the type II matching SPDC of BBO crystal and calculate the phase matching angle. The phase matching angle is the minimum cutting angle that can produce entangled photon pairs. In addition, a reference is attached to explain the steps and details of such experiments in detail.)

说明：  经典层次聚类算法DIANA，MATLAB编程，简单易懂，可以运行(Classical hierarchical clustering algorithm DIANA, MATLAB programming, easy to understand, you can run)

matlab最小二乘法，数值分析，抛物线方程(matlab least squares method, numerical analysis)

Structured covariance estimation. The routine takes a covariance matrix as input and returns the Toeplitz matrix that lies closest to it, in the sense that it minimizes the Kullback-Leibler divergence between the two. Input must be a real, square, symmetric and positive semi-definite matrix.
