一种新的复正弦信号二维频率估计算法一种新的复正弦信号二维频率估计算法(A new two-dimensional complex sinusoid frequency estimation algorithmA new two-dimensional complex sinusoid frequency estimation algorithm)

对信号进行短时傅立叶变换，输出的序列在进行循环平稳处理，最后用mesh函数进行3维画图。()

pathloss model in telecomunication example: free space, indoor pathloss, outdoor pathloss

说明：  几个小波消噪的matlab源代码，希望可以帮到大家(some examples of wavelet)

采用多孔trous算法(undecimated wavelet transform)实现小波变换，用的是一维信号 (The use of porous trous algorithm (undecimated wavelet transform) the realization of wavelet transform, using a one-dimensional signal)

视频处理中,镜头关键帧的主颜色的提取算法(video processing, the camera's key frame extraction algorithm colors)

本代码是基于LS算法的OFDM信道估计源代码(The code is based on the LS algorithm for OFDM channel estimation source code)

自己编写的MATLAB函数，实现对图像的旋转。B是原图像，灰度或彩色，alpha是旋转角度（角度或弧度单位均可），A是旋转后图像。旋转后图像信息尽可能不损失。(I have written MATLAB function, to achieve image rotation. B is the original image, grayscale or color, alpha is the angle of rotation (degrees or radians per unit), A is rotated images. Rotation after the image information as possible without loss.)

差错控制编码方向的经典书籍的matlab教程,差错编码方向的可以看看，很有用(Error control coding direction of the classic books matlab tutorial, error encoding direction can see, very useful)
