说明：  CT三维重建程序代码，正常运行，适合研究这方面的初学者学习借鉴(CT three-dimensional reconstruction program code, normal operation, suitable for beginners to learn from this aspect)

zybo的DDC用法,将的比较详细的一个好用文档(Zybo DDC usage, will be more detailed a useful document)

这是matlab中的时频分析工具箱，希望大家用得上。(This is a matlab in time-frequency analysis toolbox, I hope everyone useful.)

基于均方误差参数比较OFDM系统中LS和MMSE两种自适应信道估计算法的性能，程序开头都有英文注释，可以直接运行的~个人认为写得比较好，跟大家一起分享~(Based on the Mean Square Error Comparison of OFDM system parameters LS and MMSE channel estimation of two adaptive algorithms, procedures are available in English at the beginning of the Notes, you can directly run the ~ personally think that is better written, with the U.S. to share ~)

论文分析了合成孔径雷达图像迭代滤波处理的效果及其问题，结合统计滤波方法和小波分析方法，提出了一种基于细节补偿的MAP迭代滤波算法。实验结果表明，新的迭代滤波算法较好地解决了去噪和细节保留之间的矛盾，而且算法稳定，收敛很快。(This paper analyzes the iterative synthetic aperture radar image filtering effect and its problems, combined with statistical filtering methods and wavelet analysis method, details of compensation, a MAP based iterative filtering algorithm. Experimental results show that the new iterative filtering algorithm can solve the denoising and detail preservation conflicts between, and the algorithm is stable and fast convergence.)
