Road vehicles — Modular vehicle communication interface

I uploaded sample code for SIMPLE-algorithm and solving lid-driven cavity flow test. It has a lot of shortcomings, but I think that it will be useful for all newcomers. I intend to develop it further, but now it very slowly converges. All notes will be useful, and hope it can be discussed.

LTE协作通信系统的两种路由算法比较，AF和DF，里面有详细的仿真程序和结果图，是初学者的很好材料。(Comparison of two kinds of routing algorithm for LTE cooperative communication systems, AF and DF, there are detailed simulation procedures and results, is a good material for beginners.)

包含位置式PID算法、积分分离式PID，GPS和INS组合导航程序，可以实现模式识别领域的数据的分类及回归，预报误差法参数辨识-松弛的思想，车牌识别定位程序的部分功能，正确率可以达到98％。(It contains positional PID algorithm, integral separate PID, GPS and INS navigation program, You can achieve data classification and regression pattern recognition, Prediction Error Method for Parameter Identification- the idea of relaxation, Part of the license plate recognition locator feature, Accuracy can reach 98 .)

DVB-T 2k模式定时估计Matlab仿真。重新修改了程序。包括DVB-T信号产生，瑞利多径信道衰减，高斯噪声加入。 定时估计的粗定时用极大似然法，细定时用分散导频。首先确定导频模式，再通过相邻导频相关确定定时偏差。此方法适用于瑞利多径信道，高斯信道，也适用于莱斯多径信道。 信道估计利用DVB-T导频，LS估计，导频位置的时间插值，非导频位置频率插值，非常有效。 该程序经过多次运行无误，不足之处在于变量使用不规范，注释简单，读程序很费劲哈。 其特点是均采用经典算法，简单有效为主，对初学者很有帮助滴。(DVB-T 2k signal, timing estimation, channel estimation)
