power_switching_power_supply.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_switching_power_supply.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

用于谐波小波分析的程序，可以用于故障诊断，奇异点提取。(Program for harmonic wavelet analysis, can be used for fault diagnosis singular points.)

正交频分复用(OFDM)是第四代移动通信的核心技术,它是实现多媒体业务发展的基础.讨论了如何利用Simulink进行OFDM系统仿真,并给出了具体的仿真模型.利用仿真模型得到OFDM差错性能分析结果,通过对结果的分析,提出了改善性能的方法. (Orthogonal frequency division multiplexing (OFDM) is the core of the fourth generation mobile communication technology, it is the basis for the development of multimedia services. Discusses how to use Simulink for OFDM system simulation, and given the specific simulation model. Using the simulation model OFDM Error Performance Analysis of the results obtained through analysis of the results, proposed to improve performance.)

this m.file is a complete simulation of a chemical fermentation process which is done in Matlab. this job includes an on-line estimationn of the states of a control system and also the identification of the parameters of process. this work can be considered an identification research project to a great extent. there are also different methods to define the Q-matrix like Monte-carlo allghorithm,trial and error method or an inventive method which I will try to attach soon.
