考虑雨衰 阴影 和多径影响，部分实现了追踪测速迭代松弛算法，matlab小波分析程序。( Consider shadow rain attenuation and multipath effects Partially achieved tracking speed iterative relaxation algorithm, matlab wavelet analysis program.)

高斯消去法，用Matlab实现的。显然没有matlab自带的算法好，所以是练习以及和其他算法比较用的。(Gaussian elimination method, implemented with Matlab. Obviously there is no algorithm matlab own good, so is the practice and compare with other algorithms used.)

用Matlab软件实现CPFSK信号在AWGN环境下的性能仿真(CPFSK signals using Matlab software performance in the AWGN environment simulation,)

BPSK 解调 调制方式：BPSK 主要是解调模块的实现(BPSK DEMODULATION)

三相四线制两电平三桥臂APF，中线电流由电容中点控制，abc三相坐标系下滞环控制，matlab2006b，高版本的低通滤波器需更换(The three-phase four wire three-level two leg APF, the neutral current is controlled by the capacitor, hysteresis control, ABC three-phase coordinate system matlab2006b, low-pass filter, high version of the need to change)

在机器学习中经常会用到支持向量机，该代码是再使用支持向量机前对数据进行主成分分析的代码(We often meet support vector machine in machine learning , the code is about the principal component analysis befor using support vector machine (SVM).)
