matlab的一个应用实例，很有参考价值，希望大家都来看看吧(An application of matlab examples, good reference value, we want everyone to look at and see)

一个详细介绍Simulink仿真过程的课件，对于刚开始接触Simulink仿真的朋友们很值得一看！(Simulink simulation of a detailed process of courseware, for the beginning of contact with friends Simulink simulation is worth a visit!)

摘要:正交频分复用(OFDM)是第四代移动通信的核心技术。该文首先简要介绍了OFDM基本原理,重点研究了理想同步情 况下,保护时隙(CP)和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对OFDM系统性能的影响。在给出OFDM系 统模型的基础上,用MATLAB语言实现了整个系统的计算机仿真并给出参考设计程序。最后给出在不同的信道条件下,保 护时隙、信道估计方法对OFDM系统误码率影响的比较曲线,得出了较理想的结论。 (O FDM is the key techno logy of 4G in the field of mobile comm unication.In this article O FDM ba sic p rinc ip le is briefly in troduced.Then,the influence of CP and d iffe rent channe l e stim a tion on the system pe rfo rm ance is emp ha tica lly analyzed respectively in Gauss and R ayle igh fading channe ls in the cond ition of ideal synchronization.B e sides,based on the given system mode l O FDM system is compu te r sim u la ted w ith MA TLAB language and the refe rentia l design p rocedure is given.Fina lly,the B ER cu rves of CP and channe l e stim ation a re given and comp ared.The conclusion is sa tisfac to ry. )

此程序是matlab中有关平滑去噪中常用的小波的程序，简单使用，其中的注释详细，对每个变量的注释都很清楚(Matlab in this procedure are commonly used on the smooth wavelet denoising procedure, simple to use, with detailed explanatory notes for each variable are well aware of the Notes)

IEEE 802.11a-1999 or 802.11a was an amendment to the IEEE 802.11 wireless local network specifications that defined requirements for an orthogonal frequency division multiplexing (OFDM) communication system. It was originally designed to support wireless communication in the unlicensed national information infrastructure (U-NII) bands (in the 5–6 GHz frequency range) as regulated in the United States by the Code of Federal Regulations, Title 47, Section 15.407.

说明：  apso求解电力系统经济调度问题，可以得到每个机组的出力，并且含有多个约束条件(APSO can solve the economic dispatch problem of power system and get the output of each unit, which contains many constraints)

说明：  matlab均值平滑滤波器（3*3模板）(matlab mean smoothing filter (3* 3 templates))
