PNN

说明：  这是一个关于函数逼近的matlab程序，程序设计简单易懂，在稍微复杂的地方注有说明(This is a matlab program on the function approximation, the program design is simple and easy to understand, in the slightly more complex note has made it clear where)

Levinson/Burg/MUSIC/ARMA算法的功能模块~可直接调用！MATLAB文件，已编译！(Levinson/Burg/MUSIC/ARMA algorithm function module to directly call!)

eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital data signal from a receiver is repetitively sampled and applied to the vertical input, while the data rate is used to trigger the horizontal sweep. It is so called because, for several types of coding, the pattern looks like a series of eyes between a pair of rails. It is an experimental tool for the evaluation of the combined effects of channel noise and intersymbol interference on the performance of a baseband pulse-transmission system. It is the synchronised superposition of all possible realisations of the signal of interest viewed within a particular signalling interval.

it is for simple hill climbing algorithm

有较好的参考价值，自己编的5种调制信号，仿真效率很高的。( There are good reference value, Own five modulation signal, High simulation efficiency.)

自己编写的程序，用jacobi方法来求解对称矩阵的特征值还有用OR算法以及反幂法来求解特征值。(I have written procedures, with jacobi method to solve the symmetric matrix eigenvalue algorithm have to use OR as well as anti-power-law to solve the eigenvalue.)

rs编码仿真,搭配matlab工具箱的rs解码进行验证,绝对可用!(rs coding simulation, with matlab toolbox rs decoder to verify, absolutely free!)

刚好这里有一个现成的 ，自己编程剔除数据异常值。(Here are just a ready-made, its own programming excluding data outliers.)

铰链四杆机构的程序，用于计算其各构件的角位移、角速度、角加速度等变化情况(Hinge four-bar mechanism for calculating the angular displacement, angular velocity, angular acceleration and other changes of its components)

基于小波变换的ECG信号去噪，可以改小波基、阈值等参数完善实验效果，注释详细。尤其对这方面的初学者有参考价值。(ECG signal denoising based on wavelet transform.Wavelet basis , threshold and other parameters can be modified to improve the experimental results. detailed notes is especially valuable for beginners . )
