数据关联算法及其改进算法

余弦变换压缩，用于图像压缩，压缩比高，且压缩后图像质量仍然很好。适用于灰度图象。(Cosine Transform compression for image compression, compression ratio, and compressed image quality is still good. Apply to the gray-scale image.)

QPSK仿真，Eb/N0=0:10,得出BER与Eb/N0的关系曲线，AWGN信道(QPSK simulation, Eb/N0 = 0:10, draw BER versus Eb/N0 of the curve, AWGN channel)

利用马斯京根原理，根据水文气象等历史数据进行下一时段的预测。(According to Muskingum principle,the forecast of the next time can be drawn by the historical hydro-meteorological data.)

基本粒子滤波算法的实现, 同时包含了仿真测试案例(the basic particle filter algorithm, including a case study.)

一本很不错的SIMULINK教程，共享给大家-A very good tutorial SIMULINK, share to everyone

建立一种可以区分输入图形的形态学算法，算法的输入是这三种图形的一种（这三个图形是对湖、湾、路段的图像细化后的结果），输出是对这三种图形的识别。假设这三种图形都是1个像素宽且完全连通的，然而它们出现的方向可以是任意的。 (Graphics can be imported to create a distinction between the morphological algorithm, algorithm input is a three graphics (which is three graphics Lake, Bay, after the section of the results of image thinning), the output is on these three graphics recognition. Assume that these three are one pixel wide graphic and fully connected, but they appear to be any direction.)

说明：  用matlab编写的计算机图形学中的画线算法。包括几种经典的画线算法，如中点画线等。(Prepared using matlab draw line in computer graphics algorithms. Includes several classic line drawing algorithm, such as the dotted lines.)

提供了四种不同的采集数据，001和002是FSK2信号，003和004文件是FSK4信号，两个mat文件是广播接收FM信号和对讲机接收的FM信号，这两个文件都是基带信号，其他六个都是中频信号，载波分别是250KHz（001-004文件）和21.6MHz（AM信号abc0和abc1文件），提供这几个采集到的数据文件供大家进行程序的测试和修正(Provides four different data acquisition, 001. 002 is a the FSK2 signal, 003 and 004 file is FSK4 signal, two mat file is the FM signal received by the broadcast receiving FM signals and intercom, these two files are a baseband signal, the other six are intermediate frequency signals, the carrier is 250KHz (001-004 files) and 21.6MHz (AM signal abc0 and the abc1 files), the provision of several data files collected for program testing and remediation)

CoSaMP算法，在重构信号时，选取两倍稀疏度的原子来恢复原始信号，再删去一倍稀疏度的原子。(CoSaMP algorithm, in the reconstructed signal, select twice the atomic sparsity to recover the original signal, and then deleting the double sparsity of atoms.)
