As significant work was done in machine learning in past two decades, we have limited to recent articles in machine learning. A brief review of machine learning and its application can found in [Duttion and Conroy,1996). The most common supervised learning method and major implementation to various machine learning applications is artificial neural network as ANNs.

Matlab-based optimal excitation control system design，可以使励磁系统优化(Matlab-based optimal excitation control system design)

基本的源程序，可用于日常对matlab的学习与应用当中。(Basic source, can be used for day-to-day of the study and application of matlab them.)

描述小球在水平和竖直弹簧上的跳动模型（原创）(Describe the ball in the horizontal and vertical jumps on the spring model (original))

该代码可以实现对非平稳水文序列的消噪处理(It may realize the elimination of noise in stochastic hydrological series.)

DVB-T 2k模式定时估计Matlab仿真。重新修改了程序。包括DVB-T信号产生，瑞利多径信道衰减，高斯噪声加入。 定时估计的粗定时用极大似然法，细定时用分散导频。首先确定导频模式，再通过相邻导频相关确定定时偏差。此方法适用于瑞利多径信道，高斯信道，也适用于莱斯多径信道。 信道估计利用DVB-T导频，LS估计，导频位置的时间插值，非导频位置频率插值，非常有效。 该程序经过多次运行无误，不足之处在于变量使用不规范，注释简单，读程序很费劲哈。 其特点是均采用经典算法，简单有效为主，对初学者很有帮助滴。(DVB-T 2k signal, timing estimation, channel estimation)

镇流器功能测试系统，采用WT1600功率计和研华PCL-1733/PCL-1734/NI GPIB卡进行控制(Ballast functional test system, using WT1600 power meter and Advantech PCL-1733/PCL-1734/NI GPIB card control)

OFDM的LDPC编码调制程序，非常有用哦！经过学习，肯定可以掌握的！(The LDPC coded OFDM modulation process)
