用BP网络实现非线性函数逼近的一个简单的程序(BP network with non-linear function approximation of a simple procedure)

GPS输出的经纬度坐标转换为大地直角坐标(GPS output of geodetic latitude and longitude coordinates is converted to Cartesian coordinates)

this file simulates robust control with LMI

The Support Ve ct or Machi ne So fa r we have used a reference as sumpt ion tha t there exists a linear classifier that has a larg e ge ometric margin, i.e., whose decision b oundar y is we ll separa ted from all the training images (e xamples). Such a larg e margin classifier seems like one we would like to use. C an’t we find it more directly? Yes, we can. The clas sifier is known as the Support Ve ctor M achine or SVM for short.

基于MATLAB设计巴特沃斯低通滤波器MATLAB design Butterworth low-pass filter(MATLAB design Butterworth low-pass filter)

运用LMS、RLS、LSL等自适应滤波算法对16QAM信号进行处理，比较其误码率(Use of the LMS, RLS, LSL adaptive filtering algorithm for 16QAM signal processing, to compare the bit error rate)

实现了SPWM的逆变电路，程序运行过，可以进行FFT分析好用(Achieve a SPWM inverter circuit, run over, FFT analysis can be useful)

说明：  数学形态滤波器用于旋转机械的振动信号的降噪(Morphological noise filter for rotating machinery vibration signals)

这些文件夹里面包含着卷积码、调制、加高斯白噪声的程序、多径衰落径道的程序。。对那些初学者是很有帮助的。。。(The folder contains a convolutional coding, modulation, plus Gaussian white noise process, multi-path channel fading process. . Is very helpful for those beginners. . .)
