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.

CPM_LDPC_SCCPM
基于matlab编写的SCCPM、LDPC+CPM仿真，涉及到LOG-MAP算法，SOVA算法，LOG-BP算法等，全是本人自己编写性能超强。代码过长，每个都几百行，如果疑问联系我Q905432530。用着好一定要给好评！！(Based matlab prepared SCCPM LDPC+CPM simulation involves LOG-MAP algorithm, SOVA algorithm, LOG-BP algorithm, all my own preparation super performance. Code is too long, a few hundred lines each, contact me if doubt Q905432530)
