说明：  gsm的物理层仿真实现，仿真的目的不仅仅在于检查DSP程序实现的错误与否，还通过MATLAB制作相应的码表(gsm realize the physical layer simulation, the purpose of simulation is not merely to check the DSP program realize the error or not, through the production of the corresponding MATLAB code table)

说明：  IEEE14节点潮流计算程序。程序最初的数据模块可以修改成别的，如IEEE30节点和57节点的等等，矩阵取名用的是中文拼音(IEEE14 node flow calculation program)

Wavelet denoising For using this code need to use signal toolbox and general toolbox in your matlab In the first part of this assignment, we asked to obtain a (black-and-white) digital image of size 512 by 512 and then generate noisy image by adding a Gaussian noise but under the condition of having SNR=20dB by select the suitable value of variance for Gaussian noise formula. Second step is performing wavelet denoising using the hard thresholding (Use the db 6 for four levels) in the condition of finding the optimal thresholding value of T in terms of the SNR obtained. It means that, we should find the highest SNR value by finding the suitable value for threshold. Then we asked to do the same process but this time using soft thresholding. Finally for the last part of question one, we should compare the results of the obtained SNR with the recommendations of 3*sigma for the hard thresholding and 3/2*sigma for the soft thresholding.
