CODE

OFDM下行的仿真1、产生要传输随机数； 2、进行调制； 3、串并转换； 4、进行IFFT操作（代码中有用到共轭对称向量的IFFT为实数进行简化计算）； 5、增加循环前缀； 6、并串转换； 7、输出前滤波； 8、增加信道噪声（加性高斯白噪声）； 9、接收端串并转换； 10、去除循环前缀； 11、进行FFT变换； 12、信号解调； 13、误比特率计算； (OFDM downlink simulation 1, have to be transmitted random number 2, the modulation 3 series and transforms 4, the IFFT operation (code useful to conjugate symmetric vector of the IFFT of real numbers to simplify calculations) 5, the increase in circulating prefix 6, and string conversion 7, the output before the filter 8, increased channel noise (additive white Gaussian noise) 9, the receiver string and conversion 10, removal of cyclic prefix 11, the FFT transform 12 , the signal demodulation 13, bit error rate )

MATLAB的数字滤波器设计 (MATLAB digital filter design)

MATLAB具有强大的科学计算功能, 含有大量多目标优化分析函数。依据技术将函数在 环境下进行调用, 进行多目标优化集成系统开发, 实现数据的自动输入和输出功能, 编制了MATLAB与VB的数据接口代码, 提出程序设计时应注意的问题。(MATLAB has powerful scientific computing functions, contains a large number of multi-objective optimization analysis function. Based technology will function in the environment calls for multi-objective optimization of integrated system development, automated data input and output functions, the preparation of the MATLAB data interface with the VB code, the program design should pay attention to the problem.)

matlab programm for kmean and fuzzy cmean clustering.

用matlab编写的车牌识别程序，已经调试过了(Written by matlab license plate recognition program, has been the commissioning)

matlab code for global section

也是一本较好的图像处理与机器视觉的书籍，希望对大家有帮助，仅提供给对自己需要的朋友学习，不得用作获利工具！！(Image processing analysis and computer vision )

等高线作图的全部做法，特别适合matlab的初学者使用，基本上全覆盖了(Contour mapping approach, especially for Matlab for beginners to use, basically covering all)

差分空时编码，解码译码都有，无信道，含新版本matlab缺少的旧版函数dmodce(Differential space-time encoding, decoding decoding has no channel)

说明：  k-means算法实现以及Iris数据集(Implementation of K-means algorithm and Iris data set)
