图像压缩是数据压缩的数字图像的应用程序。在效果上，目的是为了减少图像数据的冗余，以便能够存储或传送数据以有效形式[1]。数据压缩已经成为在不同领域，如计算机科学，信息技术，通信，医药等行业在计算机科学中大多数应用需求，数据压缩被定义为科学或代表在一个紧凑的形式的信息的艺术[2]。数字图像压缩技术可分为两类：无损和有损压缩。目前的数据压缩的两个基本类别被应用于不同的领域。在无损压缩，这是最初的图像中每一个像素仍然是相同的图像解压缩后。所有的信息被完全存储。有损压缩通过永久消除一些冗余信息减少图像的尺寸。重构的图像中包含的降解到原始图像。

很我算法都会用到数据计算的问题，本程序可实现简单的数字计算（加减乘除等），对进行后面的复杂运算有一定的参考价值，-algorithm will use the data, The program can achieve Simple arithmetic (such as arithmetic), for the rest of the complex computing a certain reference value,

针对基于随机波束成形的多用户MIMO下行系统提出了三种调度算法:后端比例公平门限调度算法，后端最大值调度算法和后端比例公平最大值调度算法。通过仿真表明，这三种算法相比其他调度算法，在基本保持系统性能的前提下，能够降低反馈率，且有各自的特点和适用性:后端比例公平门限调度算法随着小区内用户数目的增多，反馈率越小，适合用户数较多的情况；后端最大值调度算法和后端比例公平最大值算法在用户数目较多的情况下，系统性能基本保持不变，且随着子信道数目增加，反馈率越小，适合天线数和用户数都较多的情况。-Based on random beamforming for multi-user MIMO downlink system proposed three kinds of scheduling algorithms: back-end proportional fairness scheduling algorithm threshold, the maximum back-end and back-end proportional fairness scheduling algorithm for the maximum scheduling algorithms. The simulation showed that the three kinds of algorithms compared with other scheduling algorithms, the basic premise of maintaining system performance, can reduce the feedback rate, and have their own characteristics and applicability: the back-end proportional fairness scheduling algorithm with the threshold number of users within a cell increases, the smaller the response rate for the number of users are more situation back-end and back-end ratio of the maxi
