nv_encd.m　卷积编码程序 viterbi.m　　卷积译码程序 其它的是viterbi.m中用到的子函数 程序来自《现代通信系统－使用matlab》英文版 已经调通！并加上了注释。 希望对大家有帮助 GOOD　LUCK！(nv_encd.m convolutional coding procedures viterbi.m convolutional decoding process viterbi.m other is used in Function procedures from the )

给出了通过matlab设计IIR低通滤波器的程序，并通过程序把在DSP中所用到的变量计算出来，很有价值。(Matlab given by IIR low-pass filter design procedures, and procedures used in the DSP in the calculated variables, very valuable.)

说明：  MATLAB图形处理工具箱~与冈萨雷斯《数字图像处理》配套(:MATLAB graphics toolbox ~ and Gonzalez, &quot Digital Image Processing&quot package)

使用ARGO数据求解经验正交函数，只给出了基本程序，无实测数据，是个小程序(ARGO data solving empirical orthogonal function, given only the basic procedures, no measured data is a small program)

利用干扰观测器+滑模控制进行机械臂轨迹跟踪，完整代码(The trajectory tracking of the manipulator with disturbance observer + sliding mode control)

这是一个基于神经网络的数字识别程序，能够识别出0~10的阿拉伯数字(This is a neural network-based digital identification procedures, to identify the Arabic numerals 0 to 10)

说明：  这是一个matlab程序用于构建人工神经网络模型，可以随意设置层数和单元个数！(This is a matlab program for building artificial neural network model can arbitrarily set the number of layers and units!)

input 3 point get a circle

心电信号RR间期检测等 (ECG RR interval detection)

在系统辨识中，关键的是系统建模这里提出了多种方法(In system identification, system modeling is the key to a variety of methods presented here)
