对光学系统中常用的正弦振幅型透射光栅进行了仿真，仿真结果有衍射图案和光强沿x轴方向的曲线。(Of the optical system used in the amplitude of the sinusoidal transmission grating-based simulation, simulation results diffraction patterns and light intensity along the x-axis direction of the curve.)

通过此程序仿真数字基带传输系统的基带信号波形。(Simulation of this process through the digital base-band transmission systems, base-band signal waveforms.)

这是关于matlab语言学习的经验，其中包括两个txt文档很方便下载，可以在手机上看，写的很好，值得看看。(This is about the matlab language learning experience, including two txt documents easy to download, you can phone point of view, well written, it is worth a look.)

该程序可以将LDPC码校验矩阵mat文件转换成文本文件(The program can check matrix of LDPC codes mat file into a text file)

This function model the troposphere based on the inputs of the user: it adds clouds, fog,cirrus, wet air and dry air

matlab程序用于对于已知程序阶数进行系统辨识，辨识出系统的传递函数(matlab program is used to program the order of the known system identification, identify the system transfer function)

时隙ALOHA协议是对ALOHA协议的简单修改，把传输时间分为一个个时隙，数据包只能在时隙的开始进行并行传输。在当前的时隙中产生的数据包只能在下一个时隙的开始进行并行传输。(Time slot ALOHA protocol is simple modification of ALOHA protocol, the transmission time is divided into a time slot, packets can only be the beginning of time slot for parallel transmission. In the current time slot of packets can only be the beginning of the next time slot for parallel transmission. )

七自由度整车模型，四个车轮的转动，纵向侧向运动，以及横摆运动，包括dugoff轮胎模型以及其中的参数(Seven degrees of freedom vehicle model, four wheel rotation, vertical lateral movement and yaw movement, including dugoff tire model and parameters which)

说明：  分数阶滤波，FRFT自适应滤波，以及其实例。 附有相对应的数据可用给的程序做处理。(Fractional order filtering, FRFT adaptive filtering, and its example. The corresponding data are attached, which can be processed by the program.)
