利用BP人工神经网络对语音特征信号进行分类(classification of Speech signal )

说明：  LTE-A中的AF和DF中继研究，比较有用(LTE-A in the AF and DF relaying research, more useful)

说明：   该程序在matlab-simulink环境下执行，名为classpiddistb2.mdl，(经典PID的扰动测试)，本人发前期发.m格式文件(NNPIDDistub2.m为神经网络动态pid抗绕程序)，本程序为前期程序的比较程序，已发于本人论文，可供借鉴和学习。(The program matlab-simulink environment, implementation, called classpiddistb2.mdl, (classical PID disturbance test), I made pre-made. M format (NNPIDDistub2.m for the neural network dynamic pid anti-around program), this procedure pre- The Comparative procedures have been made in my paper, for reference and learning.)

请用多层感知器（MLP）神经网络误差反向传播（BP）算法实现异或问题（输入为，要求可以判别输出为0或1），并画出学习曲线。其中，非线性函数采用S型Logistic函数。(Please use the Multilayer Perceptron (MLP) back propagation neural network (BP) algorithm XOR problem (input is required to determine the output is 0 or 1), and draw the learning curve. Among them, the non-linear function using S-type Logistic functions. )
