M_Files

CDMA code with errro checking and corrections..

These M-files are "Communications Toolbox" for classroom use. It is used by students taking a 4th year communications course where the emphasis is on digital coding of waveforms and on digital data transmission systems.

 Bootstrap is a data based simulation method for statistical inference. The basic idea of bootstrap is to use the sample data to compute a statistic and to estimate its sampling distribution, without any model assumption. Many technics are described with some examples in matlab.

用matlab实现了简单的图像处理，频率滤波(Using matlab to achieve a simple image processing, frequency filtering)

Maglev System Simulation Using MATLAB

偏微分方程的MATLAB解法，能快速求解，阐述了其编程思想，很实用(Solution partial differential equations )

赶火车过程仿真 一列火车从A站经过B站开往C站，某人每天赶往B站乘这趟火车。已知火车从A站到B站运行时间为均值30分钟、标准差为2分钟的正态随机变量.火车大约在下午1点离开A站。离开时刻的频率分布为 (Process simulation, a train to catch the train from A through B station station station bound for C, B Station tour someone rushed to the train every day. Known to the train station from station A to B as the average running time 30 minutes, standard deviation of 2 minutes of normal random variables. Trains leave about 1:00 pm A station. The frequency distribution for the leave time)

用simulink实现8PSK调制解调，并显示眼图和星座图(8PSK in simulink realise)

该程序实现多特征自适应阈值算法，两个matlab文件，一个为函数，该函数求出信号的特征量值并通过梯度下降法训练出其初始阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号的特征量值及其自适应阈值求出来，并一起画出图来。(The program features multi-adaptive threshold algorithm, two matlab files, one for the function,the function seek out characteristics value and initial threshold value of the signal by gradient descent , the other main function, called the function file the program seek out four signals , characteristics of each road and the adaptive threshold value,then draw them together on the map.)
