海杂波模拟和循环对消法实现杂波抑制的matlab源程序,包含不同信噪比下的目标回波以及最小二乘实现的滤波器完成杂波抑制(Sea clutter modeling and cycle cancellation method for clutter suppression matlab source code, including different target echo signal to noise ratio as well as the least-squares filter to achieve complete clutter suppression)

利用matlab自己建立光栅，别且进行方向滤波，效果十分明显(Grating using matlab to establish their own, do not and the direction of filtering, the effect is very obvious)

关于魏格纳分布的计算代码，可以得到IMF和各个特征频率以及进行希尔伯特变换。(About calculation code Wigner distribution can be obtained as well as the IMF and the individual characteristics of the frequency of the Hilbert transform.)

数字信号处理书籍的matlab程序，内含许多数字信号处理内容，值得下载(digital signal processing procedures Matlab books, containing many digital signal processing, is worth the download)

简单SENSE图像重建，即使通过反傅里叶变换重建出最终图像(The data was acquired from 4-channel array coil using EPI sequence (2-shot, matrix: 64X64, TE: 50 ms) at a 1.5T scanner. The code estimates the coil sensitivity profiles directly from the image with anatomical contrast by low-pass smoothing. Subsequently, k-space data were decimated to simulate 2.0-fold acceleration (R=2.0). Finally, using least-squares estimate, the reconstructed full-FOV spin density image is obtained)

说明：  批量下载图片，可以从FLICKER上下载图片(Batch download pictures, download pictures from FLICKER)

matlab中编写的一个计算PI参数的程序，可以自动整定控制系统的PID参数(PID controller caculate)

说明：  这是一款算法是哑奴，你可以集成到自己的demo里然后自己体验(This is an algorithmic dumb slave that you can integrate into your demo and experience for yourself.)
