在非正交（NOMA）环境下，固定功率分配和树形算法分配的比较，说明树形的优势(In the non-orthogonal (NOMA) environment, relatively fixed power allocation and distribution tree algorithm, explain the benefits of tree)

采用MATLAB 对图像进行加噪，滤波，置乱等方面的处理代码。(photo noise in matlab)

在悬架matlab仿真中，求解加速度、悬架动挠度，轮胎动位移的功率谱密度(Suspension matlab simulation, solution acceleration, suspension deflections, tire displacement power spectral density )

this code is to perform frequency shift keying modulation technique

汽车动力性，燃油经济性计算,基于MATLAB计算的，汽车理论相关内容。(Automotive power, fuel economy calculation)

根据系统的输入和输出，辨识系统的的传递函数。该系统为6阶系统，通过降阶降为2阶后，加入状态反馈和状态观测器，调整参数使2阶系统稳定，最后用于控制原6阶系统。阶跃响应和bode图效果都不错。(Based on the input and output of the system, the transfer function of the system is identified. The system is a 6 order system. After the order is reduced to 2 order, the system is added with the state feedback and the state observer, which adjusts the parameters to make the 2 order system stable. Finally, it is used to control the original 6 order system. Step response and Bode figure results are good.)
