信道编解码中的turbo编解码程序，采用了多种解码算法，进行了性能比较，信道模拟高斯白噪声信道(Channel of the turbo codec codec procedures, using a variety of decoding algorithms, a performance comparison, channel analog Gaussian white noise channel)

A direct search method instead of a coordinate descent iterative LMI algorithm

用matlab编程的鱼群模拟，比较好用，希望能有所帮助(Simulation using matlab Programming fish, relatively easy to use, and I hope to be helpful)

matlab神经网络，用于数据拟合及数据模拟预测(matlab neural network for data fitting and data simulation and prediction)

用于生成FPGA中RAM所需要的初始化文件dds.mif,此文件生成的是余弦波形。(This document of .m can generate document of .mif to provide data for RAM of FPGA.)

在机器学习中经常会用到支持向量机，该代码是再使用支持向量机前对数据进行主成分分析的代码(We often meet support vector machine in machine learning , the code is about the principal component analysis befor using support vector machine (SVM).)

该程序是用matlab语言实现的对瑞利信道的描述，读者可以一试(The program is described by Rayleigh channel matlab language, readers can try)

因子分析是指研究从变量群中提取共性因子的统计技术。最早由英国心理学家C.E.斯皮尔曼提出。因子分析可在许多变量中找出隐藏的具有代表性的因子。将相同本质的变量归入一个因子，可减少变量的数目，还可检验变量间关系的假设。(Factor analysis is the study of common factors extracted from the variable group statistical techniques. First proposed by British psychologist CE Spearman. Factor analysis can identify a representative factor to hide many variables. Will be essentially the same variables into one factor, can reduce the number of variables, but also test the hypothesis that the relationship between variables.)
