用simulic编写了生成信号 很详细很好用呢(singal simulic)

AfxGetApp()应用，比较简单的说明，我从网上找的。(AfxGetApp (), relatively simple explanation, I find from the Internet.)

是我见过讲的最详细的关于稀疏信号的书，讲解了稀疏分解，以及书后的程序都是很好用的(Ive seen talking about the most detailed book about the sparse signal, explained the sparse decomposition, and program books are well used after)

LDPC码的软判决译码算法，概率域LLR—BP算法，其中，概率信息以对数似然比的形式表示。(The decoding algorithm of LDPC . The LLP-BP algorithm of probability field,in which,the probability informationv expressed by the form of log likelihood ratio.)

base_band.rar文件解压后可以在matlab平台直接编译运行，实现通信系统的升余弦基带 成型处理，码元速率，采样率、滚降系数都可以灵活设置，特别方便学习通信的同学加深对基带信号的理解。(base_band.rar unzip the files can directly compile and run matlab platform to achieve communication system raised cosine baseband shaping processing, chip rate, sample rate, roll-off factor can be set flexibly, in particular, to facilitate students to learn to communicate better to the base band signal understanding.)

测试以下图像信息 1。结构内容（SC） 2。均方误差（MSE） 3。峰值信噪比（PSNR值） 4。归一化互相关（NCC） 5。平均差（AD） 6。最大的差异（MD） 7。归一化绝对误差（NAE）(Image/Picture Quality Measures In this application, different image quality measures are calculated for a distorted image with reference to an original image. To test the application, a set of 20 distorted images is included in this package. The list of Image Quality measures implemented in this package include, 1. Structural Content (SC) 2. Mean Square Error (MSE) 3. Peak Signal to Noise Ratio (PSNR in dB) 4. Normalized Cross-Correlation (NCC) 5. Average Difference (AD) 6. Maximum Difference (MD) 7. Normalized Absolute Error (NAE) Refer Reference.png for the mathematical expressions implemented in this package. Original images are kept in the folder OriginalImages . Distorted images are kept in the folder DistortedImages .)

This is matlab code for stockwell transform as a time frequency distribution for feature extraction that was developed by Doctor stockwell
