System-stabilization

不错的OFDM系统仿真程序。包括了整个系统所需的仿真程序。(Good OFDM system simulation program. Including the entire system simulation program required.)

学习matlab很好的PPT课件，还有很多经典程序(matlab study)

Matlab编写的加窗傅里叶变换及原理。。。(Written in Matlab and principles of windowed Fourier transform)

说明：  mylsb.m是个非常完整的LSB密写源码并且密写和提取都在里面，图片我没上传，你只需要添加一个图片文件就可以了，记住图片必须是灰度图片，如果是RGB，我转换的代码也在里面很有意思哦。weipingmian.m是个提取图像位平面的程序，图片也是需要你自己加载，最后一个就是8*8块的图像DCT变换。(mylsb.m is a very complete source of LSB Steganography Steganography and extraction, and are on the inside, I did not upload pictures, you only need to add a picture file on it, remember the image must be a grayscale image, if it is RGB, I converted the code is also very interesting inside Oh. weipingmian.m is a program to extract bit-plane images, pictures, you also need to load the last one is 8* 8 DCT transformed image.)

说明：  对数值进行分析，AP聚类算法是基于数据点间的"信息传递"的一种聚类算法。与k-均值算法或k中心点算法不同，AP算法不需要在运行算法之前确定聚类的个数。AP算法寻找的"examplars"即聚类中心点是数据集合中实际存在的点，作为每类的代表(For numerical analysis, AP clustering algorithm is based on the "information transfer" between data points. Unlike k-means algorithm or k-center algorithm, AP algorithm does not need to determine the number of clusters before running the algorithm. The "examples" searched by AP algorithm is the actual points in the data set as the representative of each class)

在OFDM仿真模型的基础上用MATLAB语言编写出OFDM发送、信道及接收整个系统,在系统仿真正确的前提下,对循环前缀、信道估计等性能改善方法进行进一步仿真验证 (In OFDM simulation model based on the use of MATLAB language to send the OFDM, channel and receive the entire system, in the system under the premise of the correct simulation of the cyclic prefix, channel estimation methods for further performance improvement simulation)

光纤Bragg光栅的1阶2次模（LP02）的有效折射率和谐振波长的计算测试程序，欢迎拍砖

利用M函数仿真扩频通信系统。6个用户的CDMA的同步通信系统，每个用户利用L＝31的Gold码，进行扩频，信道为AWGN信道，接收端利用匹配滤波器进行检测。绘出当N＝10000个发射比特下，SNR＝0：15（dB）时的误码率曲线。 (M function simulation using Spread Spectrum Communication System. 6 simultaneous users of CDMA communication system, each user of the L = 31 the use of Gold codes for spread spectrum, channel for the AWGN channel, the receiving end to detect the use of matched filter. Drawn when N = 10000 bits of transmission, SNR = 0:15 (dB) when the bit error rate curve.)

QPSK调制的程序，可以正确运行，对初学者很有帮助(QPSK modulation procedure can correct operation, useful for beginners)

经典的扩展卡尔曼滤波卡尔曼滤波程序，首先对非线性函数取一阶近似，生成近似的新型函数，然后进行卡尔曼滤波，通过一步状态和估协方差估计产生新息，然后生成状态预测(Classical extended Kalman filter, Kalman filter procedure, first take the first order approximation of nonlinear function to generate the new function approximation, and then proceed to the Kalman filter step state estimate covariance is estimated to generate new interest, and then generate the state prediction)
