说明：  对成型脉冲串进行中频调制，输出为复基带信号。还可通过各种自定义信道。(On the frequency modulated pulse train forming the output for the complex baseband signal. Can also be customized through various channels.)

LDPC码的完整的编译码，实现了图像的加水印，去噪，加噪声等功能，语音信号的采集与处理，数字信号处理课设。( Complete codec LDPC code, Realize image watermarking, de-noising, plus noise and other functions, Acquisition and Processing of the speech signal, digital signal processing class-based.)

googleMap截取，功能异常的强大，全自动抓取，自动聘图！(GoogleMap interception, dysfunction powerful, fully automated crawler to automatically engage Chart!)

分别用三段直线和imadjust函数对图像进行对比度增强，并可以比较结果。(Three lines and imadjust function of image contrast enhancement, and can compare the results.)

该程序实现了压缩感知理论中采用矩阵的优化。在压缩感知理论中，要求采样矩阵与稀疏矩阵的相关性越低越好。该代码采用一种交替投影的方法实现采用矩阵的优化，有效降低其相关性。(The program to achieve the optimization of the use of matrix theory compressed sensing. Requirements of the sample matrix and sparse matrix theory of compressed sensing, the lower the better. The code uses an alternating projection method to achieve the optimization of the use of matrix to effectively reduce the correlation.)
