讲述4G通信OFDM技术理，介绍了该技术的基本原理，信道估计原理，同步原理以及峰均比抑制技术。(About 4G OFDM technology communication manager, describes the basic principles of the technology, channel estimation theory, the synchronization principle and PAPR reduction techniques.)

广义互相关函数，用于时延估计的运算，很好用。(Generalized cross-correlation function for time delay estimation of the operation, it just works.)

fisher辨别分析方法的修改版，这是我们做掌纹识别的的时候自己修改后的程序，仅供参考哦完整源代码，已通过测试。 (fisher analysis to identify the modified version, which is the time to do their own palm printts to identify the revised procedures, only reference Oh complete source code, has been tested. )

MATLAB的cca算法实现，输入数据集，输出系数矩阵(Realization of CCA algorithm in MATLAB)

采用数学建模方法解决统计问题，包含数据的统计描述与分析，回归分析，含有PPT讲解(Mathematical modeling approach to the use of statistics, including data description and analysis of statistics, regression analysis, with PPT on)

51全面参考书籍，非常好，有需要的请尽快下载。(51book，download be quick !)

Run the ROI file by issuing the command ROI in the command window and a GUI screen will pop up, the screen may be used for selecting a Region of interest while viewing the full length movie and adjusting the region of interest accordingly, after hitting save the GUI will dismantle the movie to seperate images and will save them in current folder.The GUI panel is self explanatory and as such does not require any further explanations

说明：  设计产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，使用矩形窗设计不同特性的数字滤波器对信号进行滤波处理，分析所设计滤波器(画出了频率特性曲线)，并对信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，同时设计出了一个友好的人机交互界面。(Designed to produce a continuous signal, including low frequency, medium frequency, high frequency components, its sampling, spectral analysis, using rectangular windows of different characteristics of digital filter design the signal filtering, analysis of the designed filter (to draw the frequency characteristic curve), and signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, the mean time, a friendly interactive interface.)

基于压缩感知理论的recPF重构算法,recpf为最新的重构算法，比之前omp之类算法，效果更好(Based on the theory of compressed sensing reconstruction algorithm recPF )
