现代通信系统（实用MATLAB)第二章程序(Modern communication systems (useful MATLAB) Chapter II procedure)

说明：  matlab下的FSK程序，很不错的代码，希望可以帮助到有需要的人(matlab under FSK procedures, very good code, hope to help the needy)

循环位移函数，离散傅里叶函数必备工具之一。(Cyclic displacement function, discrete Fourier one of the tools necessary functions.)

自己编的5种调制信号，借鉴了主成分分析算法（PCA），用于信号特征提取、信号消噪。( Own five modulation signal, It draws on principal component analysis algorithm (PCA), For feature extraction, signal de-noising.)

这是MATLAB学习LSDA降维方法的核心程序，将降维后的特征用支持向量机进行训练和识别！(This is a MATLAB dimension reduction methods to study the core of LSDA process will feature after dimension reduction using support vector machine training and recognition!)

this code is for array factor

一种非线性流形学习和维度缩减的算法，可以用来对数据进行降维和数据可视化。(Locally Linear Embbedding)

说明：  基于MTALAB的现代测试技术数据处理的典型程序(Modern testing technology based on MTALAB typical data processing procedure)

包含平方根容积卡尔曼滤波（CKF），无迹卡尔曼滤波（UKF），扩展卡尔曼滤波（EKF）的matlab仿真程序。(Square root volume contains Kalman filter (CKF), unscented Kalman filter (UKF), extended Kalman filter (EKF) of matlab simulation program.)

一个粒子滤波简单的例子。运行方法：解压之后，放到工作目录，运行PF_ex1.m(a simple example of particle filter.)
