cliping and filteing technique in papar reduction

FFT程序，在做OFDM时是必要的模块，很有用，在matlab上仿真实现。(FFT program, is necessary when doing OFDM module useful in matlab Simulation. )

说明：  选择“BreastCancer”数据集，使用支持向量机(SVM)对其进行分类。作为对比，第一次对特征集直接进行支持向量机分类，第二次对特征集进行主成分分析法的特征提取后，再对特征提取后的特征集进行支持向量机分类。并且对比和分析了两次分类的结果。(The BreastCancer data set is selected and classified by Support Vector Machine (SVM). For comparison, the first time the feature set is classified directly by support vector machine, the second time the feature set is extracted by principal component analysis, and then the feature set is classified by support vector machine. The results of the two classifications are compared and analyzed.)

这个源码提供了穿墙雷达反向投影成像算法的实现(backprojection（BP）算法)

qpsk调制在瑞利信道中的性能仿真，以及各个阶段信号的星座图仿真(qpsk modulation performance in Rayleigh channel simulation, as well as the various stages of signal constellation simulation)

一则matlab语言下的二维格子玻尔兹曼方法算例，圆柱绕流运动(A two-dimensional lattice Boltzmann method in MATLAB language is used to illustrate the flow around a cylinder)

gmsk的matlab实现，可直接运行，自己编写的，请高手指点(GMSK matlab to achieve the direct running, I have written, please expert advice)

matlab 数值分析于应用中的一些很用的 基本代码。(Matlab numerical analysis in the application of some very basic code.)

说明：  IEM仿真程序，可以高效的计算高斯面等粗糙面的后向散射系数(IEM simulation program, can be highly effective in terms of Gaussian faces rough surface after the backscattering coefficient)

说明：  经典ESPRIT算法，在等间距接受阵列的条件下，直接估计出我们想要接收信号的角度。八个接收天线，二个目标信号，噪声为高斯噪声。(Classical ESPRIT algorithm, such as spacing in the array to accept the conditions, we want to directly estimate the received signal point of view. Eight receiving antennas, two target signal and noise as Gaussian noise.)
