MATLAB编写的采用二相键控扩频通信仿真程序(MATLAB prepared by the two phase shift keying using spread spectrum communications simulation program)

此源代码是基于COM和ADO的数据库编程，用到了VC++6.0和ACCE(This source code is based on COM and ADO database programming, using the VC++ 6.0 and ACCE)

说明：  这个TIMEIT Benchmark用来统计用户算法的性能，只需要将你的函数句柄传递给TIMEIT.M，它就会算出循环次数等。(This TIMEIT Benchmark users for statistical performance of the algorithm, only need to handle your function passed to TIMEIT.M, it will calculate the cycle frequency.)

HI THIS IS MATLAB TUTORIAL

一本很好的线性控制系统分析的资料，讲述了线性控制系统的基本知识已经相应的matlab操作。(Linear control system analysis)

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.
