自己写的提取音频信号mfcc参数的算法，用matlab实现，欢迎大家参考(Write their own audio signal MFCC extraction algorithm parameters, using matlab to achieve, welcome to the reference)

是一个四发四收的球型译码程序，编码是卷积码，调制方式是BPSK，用Vblast来实现解码。(Is a collection of four four-ball type decoding procedures, coding is a convolutional code, modulation is BPSK, used to achieve the decoding Vblast.)

采用matlab里面的线性回归函数regress进行的分析，还画出了三维图。(Based on matlab inside of linear regression function regress analysis and drew out the 3d map.)

利用训练后的神经网络，对已知的声音进行分类，并计算误差率。能够很好的预测声音的种类(The trained neural network is used to classify the known voice and calculate the error rate. It can predict the type of sound very well.)
