Description: This package contains code for solving seven optimization problems.
-The main directory contains MATLAB m-files which contain simple examples for each of the recovery problems. They illustrate how the code should be used (it is fairly straightforward). The prefixes on the example files are as follows:
"l1eq" = L1 minimization with equality constraints,
"l1qc" = L1 minimization with quadratic (L2 norm) constraints,
"l1decode" = L1 norm approximation (for channel decoding),
"11dantzig" = L1 minimization with minimal residual correlation (the Dantzig selector).
"tveq" = TV minimization with equality constraints,
"tvqc" = TV minimization with quadratic constrains,
"tvdantzig" = TV minimization with minimal residual correlation.

Description: 感觉这份代码中最有价值的应该是水声信道的建模，该源码来自美国 Parastoo Qarabaqi, Northeastern University, 2013其次其提供了基于l1范数下PCA处理算法，来对经由水声信道的信号进行处理给出误码率图，启动比较程序需要先使用信道生成函数对信号进行生成。(The most valuable part of this code is the modeling of underwater acoustic channel. Secondly, it provides a PCA processing algorithm based on L1 norm to process the signals passing through the underwater acoustic channel and gives a bit error rate chart. To start the comparison program, the channel generating function is needed to generate the signals first.)

Description: 动态压缩感知（DSC）是压缩感知领域中一个重要的研究分支，它是近几年新兴起的一种信号处理与分析方法，与传统的压缩感知理论不同，DSC研究的对象是稀疏时变信号，并且已在视频信号处理和动态核磁共振成像等方面显示出了强大的应用潜力。本节正是在此基础上，提出了一种用于多普勒频率跟踪估计的DSC方法。首先，通过前一跟踪时刻所得到的先验DOA稀疏信息，获得当前跟踪时刻信号向量中各位置非零元素的分布概率，继而建立起动态DOA的稀疏概率模型。然后，采用加权l_1范数最小化方法重构出当前跟踪时刻的信号向量，从而确定非零元素的位置，获得DOA的实时估计值，最终实现运动目标的动态DOA跟踪。(L1 norm deals with DOA estimation)
