IMM_nine

ofdm信号的matlab实现，采用qpsk调制，并绘出误码率曲线(the simulation of OFDM)

说明：  利用simulink的s-function方式仿真一个单径瑞利信道，其多普勒谱为经典谱(Simulink using the s-function simulation of a single-mode Rayleigh channel diameter, the Doppler spectrum for the classical spectrum)

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

程序实现设计一单一感知器神经元以及采用神经网络拟合奇异函数。压缩包中还包含相关的参考资料。(Design a program to achieve a single sensor neurons and neural networks fitting singular function. Compressed package also contains the associated reference materials.)

能够进行简单的字母识别，基于matlab实现(Can be a simple letter recognition, based on matlab implementation)

视频跟踪的光流法，本方法用matlab仿真(optical flow)

说明：  matlab 实现dbscan 这是一种基于密度的聚类分析算法，可以发现任意形状的簇，可以发现噪声点。(Realization of DBSCAN with MATLAB This is a density based clustering analysis algorithm, which can find clusters of arbitrary shape and noise points.)

一种实现matlab和c#结合的小例子，有待进一步改进(An implementation matlab and c# combination small example, be further improved)
