代码说明:

用(7,4)线性分组码为例,采用和积算法进行译码。和BPSK译码进行对比,得出结论。用和积算法进行译码,在信噪比较低的情况下,和积算法译码不如未编码译码。当信噪比超过6dB左右时,译码效果好于未编码译码

    给定小波母函数,要求做连续小波变换,变换结果以图像形式给出(尺度-位移),说明并在图像上标出信号有哪几个成分。(For a given mother wavelet function, required to do continuous wavelet transform, transform results are given in the form of images (scale- displacement), indicating that the signal in the image on the marked which of several components.)

  • Image-Fusion-using-Cross-Bilateral-Filtering-base
    The Cross Bilateral filter can enhance the PSNR of multi focus images that is in image fuison. Bilateral filtering is a local, nonlinear and non- iterative technique which combines a classical low-pass filter with an edge stopping function that attenuates the filter kernel when the intensity difference between pixels is large. As both gray level similarities and geometric closeness of the neighboring pixels are considered, the weights of the filter depend not only on Mahalanobis distance but also on the distance in gray/color space. The advantage of the filter is that it smoothes the image while preserving edges using neighboring pixels. CBF considers both gray-level similarities and geometric closeness of neighboring pixels in image one to shape the filter kernel and filters the image two.
