An efficient algorithm for identification of PIL on Solar Dynamic Observatory (SDO) Helioseismic and Magnetic Imager (HMI) magnetograms. Detailed description will appear in the paper: Volobuev, D.M. Polarity-Inversion Line Preceding X-class Flare, Solar Physics, Initial data (65 megabyte .fits magnetograms) can be downloaded from http://hmi.stanford.edu/ - Model_test_PIL_Open.m script - calculates parameters of the example(simulated S-curve) - SDO_PIL_Open.m script - identifies PIL on SDO magnetogram and calculates its parameters - 5 functions are used within these scripts

自己编写的fft变换的MATLAB源代码！里面还有操作过程。很好用哦(Have written MATLAB s fft transform the source code! There is also the process. Oh, well used)

DS-CDMA仿真程序,有大量注释,很值得一看,全面的讲解了CDMA的原理.(DS-CDMA simulation program, has a large number of notes, it is worth a visit, a comprehensive explanation of the principle of CDMA.)

对一段语音进行端点检测并对检测的语音画出方框图，不同于一般只画竖线(Endpoint detection of a voice to draw the block diagram and detection of voice is different from the vertical line is generally drawn)

系统的介绍了STK中Astrogator模块的使用情况，并对STK软件进行了一个全面的介绍，是stk学习的一份好资料(STK & Astrogator)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)

DHMM，离线隐马尔科夫模型用于模式分类的好例子，特征采用Kmeans进行离散化。(DHMM, off-line Hidden Markov Model good example for pattern classification, feature discretization using Kmeans.)
