This is the JPEG compression

组合需要读取的图像文件直接路径和间接路径，读取jpg图像，并计算压缩图像和无压缩图像的均方值和LMSE(Combination needs to read the image files of the direct path and indirect path, to read the jpg image, and calculate the mean square value of compressed images and uncompressed images and LMSE)

关于OFDM的调制仿真，其中使用是QPSK调制，包含FFT、循环前缀、加窗等基本过程。(OFDM modulation on the simulation, in which a QPSK modulation, contains the basic process FFT, cyclic prefix, windowing and so on.)

matlab程序，经过多次调试可以运行，包含多个文件，可以准确得到结果。(matlab program, after several debugging can run, contain multiple files, you can get accurate results.)

说明：  BD-OFDM的接收和发射，是用Matlab编程实现的++matlab，程序比较简洁，易懂。(BD-OFDM receiver and the launch is the use of Matlab programming of the++ matlab, procedure is simple and easy to understand.)

Matlab code for succsesive approximation ADC

说明：  调频立体声基带信号 产生和测试模型 文件名：ch5example5.mdl(FM stereo baseband signal generator and test the model file name: ch5example5.mdl)

文章对几种常用的基于循环前缀(CP)的最大似然同步算法进行了分析，并对其频偏估计方差进行了比较；同 时针对基于CP 的同步算法在多径衰落信道下性能较差的情况，提出了一种改进的CP 同步算法并进行了仿真，结果表明相比 于原ML 算法，文中算法在多径信道下可有效提高频偏估计性能。(】This paper does some research on multiple maximum-likelihood (ML) algorithms based on cyclic prefix (CP) and compares variances of frequency-offset estimation After the analysis of the bad performance of CP based algorithms in multi-path fading channels, an improved CP algorithm is proposed and the simulation shows that this algorithm can improve its performance effectively in multi-path fading channels.)

matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第三程序设计(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the third program design)

掷骰子x，相同的骰子如果大于Y，得分为零，否则为个点数和。多次掷骰子观察概率情况(Dice x, the same dice if greater than Y, score zero points and one otherwise. Probability of observing multiple dice)
