this is the code for image compression using neural network.

通信系统中对快速傅里叶变换的MATLAB仿真程序(Communication systems in the fast Fourier transform MATLAB simulation program)

使用ppt对扩频通信的原理进行详细介绍,然后对其原理利用matlab7.0版本软件进行simulink仿真框图设计，进行仿真试验，适合教师教学和学生自主学习使用！(Using ppt on the principle of spread spectrum communication to conduct a detailed introduction, and then their version of the principle of the use of matlab7.0 diagram simulation simulink software design, simulation tests, suitable for teachers and students to use self-study!)

说明：  该算法是rock算法的主体算法，主要用于数据的聚合处理(The algorithm is the algorithm of the main algorithm rock, mainly for data aggregation processing)

this code for pr classroom code useful

说明：  dpd的matlab程序5个，需要配套使用，包含saleh模型，多项式模型和volterra模型(dpd using matlab, Including Saleh model, polynomial model and Volterra model)

精通GUI图形界面编程(MATLAB) 施晓红版 外加几个相关的教程，不如施晓红的系统，但是有参考价值 图书馆热门书籍，专业书籍，一般书店买不到(Proficient in GUI graphical interface programming (MATLAB) Xiaohong Shi version plus some related tutorial, there is reference value for the library popular books, professional books, general bookstore can not buy)

四步搜索算法对三步算法进行了适当的改进，在一定程度上弥补了TSS算法在估计细小运动时的不足，并加入了半途中止的策略，进一步提高了搜索精度 (Four-step search algorithm for three-step algorithm to improve the appropriate, to a certain extent make up for the TSS algorithm in estimating the inadequacy of a small movement, and joined the mid-suspension strategy to further improve the search accuracy)

一个GUI界面，包括图像反转、对数和幂次变换、直方图均衡化等等(A GUI interface, including image inversion, logarithmic and power transformations, histogram equalization, etc.)
