Understanding Star Grounding

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％， 不加入噪声，进一步生成某个特定的中频信号(The baseband signal is generated using Matlab GPS C/A code. (1) generate satellite PRN number " 5" is a set of C/A code (2) loop generates 25 navigation data, GPS time can be filled with a fixed known value (3) generated C/A code spread spectrum signals, each C/A code chip sample data is given 4 (4) a baseband signal using a square wave signal with a level of 0 and a duty cycle of 50 , the noise was not added, and further generates a a specific frequency signal)

Dynamic Benchmark Problem

matlab神经网络手册，想打印出来看的可以下载哦(matlab neural network handbook, would like to print out looking at can download Oh)

计算压力传感器的总精度，包括非线性、迟滞、重复性。(Calculated the total accuracy pressure sensor)

here to import the pictures and how to segment the picture. how to add the noise. some screen shots will be added this file.

灰色模型（GM)。如果一个系统具有层次、结构关系的模糊性，动态变化的随机性，指标数据的不完备或不确定性，则称这些特性为灰色性。具有灰色性的系统称为灰色系统。在灰色系统理论中，利用较少的或不确切的表示灰色系统行为特征的原始数据序列作生成变换后建立的，用以描述灰色系统内部事物连续变化过程的模型，称为灰色模型，简称GM模型。(GM 1 to 1)

The modeling of the three phase induction machine is explained in this matlab simulink model.

说明：  可以利用元胞自动机模拟疫情发展情况，并且有详细的论文说明，语义解释(Cellular automata can be used to simulate the development of epidemic situation)

用kalman滤波算法来跟踪鼠标, 小有意思的程序, 有助于理解kalman算法(Using kalman filter algorithm to track the mouse, a small interesting programs, help to understand the kalman algorithm)
