经过验证的维特比编译码MATLLAB程序，每行代码都有详细的备注 (Proven Viterbi than the codec MATLLAB program, each line of code to have detailed notes)

基于星座图的QPSK仿真，易于理解QPSK的原理(QPSK constellation based on simulation, and easy to understand the principles of QPSK)

采用bp神经网络对函数y=sin（x）进行训练，然后用测试集对训练的函数进行测试，也就是函数逼近sin（x)的曲线(Bp neural network using the function y = sin (x) for training, and then use the test set to test the training function, that is, function approximation sin (x) curve)

基于matlab simulink 的六连杆模型，可以对速度，加速度，位移进行仿真，不用推倒数学公式，仿真容易实现(Based on the six linkage matlab simulink model, for speed, acceleration, displacement simulation, do not tear down the mathematical formulas, easy to implement simulation)
