denoisingWavelet
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.

caponBF
DOA 中的caponBF, 阵列信号处理的一个基本问题就是确定同时处在空间某一区域内的多个感兴趣的空间信号的方向或位置,即实现信号的分辨和定位,这也就是雷达、声纳最重要的任务之一,为了解决这一基本问题,主要采用常规波束形成法。(DOA of caponBF, a fundamental problem in array signal processing is to determine in space at the same time more interested in a particular area of space signal direction or position, namely the realization of signal resolution and positioning, which is one of the most important task in radar, sonar, in order to solve the basic problem, mainly using the conventional beam-forming method.)

pso123
说明: 首先介绍一下早期的简单模型,即Boid(Bird-oid)模型。这个模型是为了模拟鸟群的行为而设计的,它也是粒子群优化算法的直接来源。(Because the simulation is too simple and far away from the real situation, a random variable is added to the velocity term, that is, in each iteration step, in addition to meeting the "nearest neighbor velocity matching", a random variable is added to each step of the speed, so that the whole simulation looks more realistic.)
