流形学习算法，程序中也包含了多种经典的模式识别算法,如MDS、PCA。(Manifold learning algorithm, the program also contains a variety of classical pattern recognition algorithms, such as MDS, PCA.)

说明：  基于matlab的lpc分析，即线性预测。分析较为全面，且测试通过。(The lpc matlab-based analysis, that is linear prediction. More comprehensive analysis and test. )

用于产生QPSK卷积码的程序，已经完整运行过，可运行(QPSK convolutional code used to generate the program has had a full run, run)

本算法能够按照两种策略生成并绘制随机图，但是对于生成的随机图的属性分析不够完善，从代码中能够看出作者并没有完成本算法关于“平均路径长度”、“聚类系数”和“平均度”三个属性的求解。(The algorithm is able to follow two strategies to generate and draw random graph, but for the properties generated random graph analysis is not perfect, it can be seen from the code of the algorithm is not complete on the "average path length", "clustering coefficient" and "the average degree of" solving the three properties)

利用Matlab对通信系统仿真的基本思想和方法； 利用MATLAB的集成仿真环境Simulink对双边带幅度调制系统进行仿真 (Matlab simulation of communication systems using the basic ideas and methods integrated simulation environment using MATLAB Simulink bilateral system is simulated with amplitude modulation )

Digital signal processing

使用k-means算法对样本空间中的未分类的点进行聚类。(K-means algorithm using the sample space clustering unclassified points.)

Space-time trellis encoder/decoder for QPSK modulation 2 bits per second per Hertz

只需修改路径，就可处理txt文件心电数据，要求此心电数据必须是R波的横坐标，可画散点图，密度图等(use the matlab to process the ECG data,detect the R-point.)

nginx源码分析，全面易懂。正在研究nginx的朋友可以看看。(nginx source code analysis, comprehensive and easy to understand.Studying nginx friends can see.)
