说明：  用于matlab频域分析、功率谱密度分析(fft and psd by matlab)

this program is for frquency shift keying

lib svm is support vector machine which can be used in classification and regression test. thanks for open source

蚁群算法,这里只有关键的算法函数，并不包括主函数。其中ACATSP为蚁群算法的关键函数。G2D是一个辅助函数，绝大多数蚁群算法源码不包括这个函数。另外还有一个画图的函数。(ant algrithm)

验证功率倒置算法对gps信号中大功率单频信号的消除，包括gps信号的产生和算法的实现(Verify power inversion algorithm gps signal in high-power single-frequency signal to eliminate, including the gps signal generation and algorithm)

程序实现了生成决策树并使用决策树对离散特征向量进行分类。在判断是否要继续生成叶节点时采用entropy来作为impurity的measurement.(Program and use the decision tree decision tree to generate discrete feature vectors for classification. In determining whether to continue generating leaf nodes using entropy as the impurity of the measurement.)
