代码说明:

压缩感知,又称压缩采样,压缩传感。它作为一个新的采样理论,它通过开发信号的稀疏特性,在远小于Nyquist 采样率的条件下,用随机采样获取信号的离散样本,然后通过非线性重建算法完美的重建信号。它的关键就是信号重建算法,这里提供了自己编写的贪婪算法OMP,matlab程序,包括测试程序在内。

  • ICAcrosstalkerror
    我自己编的串音误差计算函数,对公式进行了一定化简,比本网站其他同类计算函数运算速度要快。用于盲源分离的质量评价,另外还包含ICA中有关性能评价指标的文章。(My own series of crosstalk error calculation function, to the formula for a certain simplification, other than this site similar calculation function operation faster. Quality Evaluation for blind source separation, also contains articles on the ICA performance uation index.)

    AFSA_fxy是用人工鱼群算法(artificial fish swarm algorithm)解决二元函数寻优问题。文件打开后运行AFSA_fxy.m文件即可得到结果,代码中有详细注释,方便修改。运行示例已经保存为图片附在压缩包中。(AFSA_fxy is (artificial fish swarm algorithm) to solve the optimization problem with a binary function AFSA. Run AFSA_fxy.m file to get the file to open the result, the code has detailed notes, easy to modify. Run the sample has been saved as a picture attached to the compressed package.)
