costas的matlab代码，广泛应用于现代通信领域中(costas the matlab code, widely used in the field of modern communications)

This simulation by MATLAB s simulink for boost converter circuit "HIGH STEP-UP CONVERTER"

说明：  在粒子滤波器框架下，选取区域协方差矩阵特征对运动独立的目标进行描述.(an adaptive template update method base on region covariance descriptor to track the target using particle filter algorithm in a complex circumstance. )

说明：  语音增强的谱减法算法实现，要有一个wav格式的声音文件(Spectral subtraction speech enhancement algorithm, there must be a wav sound file format)

The disparity map forms the basis of many computer vision techniques. A disparity map is effectively a limited 3D model

用matlab模拟光的干涉实验，两个相干光源干涉实验(Matlab simulation light interference experiment )

非常好的M_QAM调制解调程序，具有可视化用户界面，可以查看调制解调过程中每一步的调制图像和频谱(Modem M_QAM very good program, with visual user interface, you can view the modem every step of the process of image and spectrum modulation)

直接将秘密图像的高4bit隐藏在RGB载体图像的R,G,B层中所选的那一层的低4bit(Directly to the secret image hidden in the high-4bit RGB vector images R, G, B layer, then a layer of selected low-4bit)

说明：  8. 单径瑞利信道中的四发四收V-BLAST： (1) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量16QAM调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。 (4 Explain the working principle of convolutional encoding and decoding. Please use the Simulink simulation convolutional coding and Viterbi decoding method used to decode, in which the encoding, decoding all 8 single-path Rayleigh channel of the four rounds of four closed V-BLAST: (1) Please design a specific The guide-assisted channel estimation method, using Simulink for simulation, measurement 16QAM modulation bit error rate performance. Draw-bit signal to noise ratio and channel estimation mean square error curve, draw-bit signal to noise ratio and bit error rate curve.)

说明：  自相关函数和互相关函数的matlab计算和作图，这个是信号分析里的概念，他们分别表示的是两个时间序列之间和同一个时间序列在任意两个不同时刻的取值之间的相关程度。(Self correlation function and cross-correlation function of matlab calculation and drawing, this is a concept in signal analysis, they are respectively represent the is between any two different time value relevance of the two time series and the same time series.)
