matlab中利用互相关算法来计算两信号波形的时延差(To calculate the difference between two signal waveform delay using cross-correlation algorithm based on matlab)

matlabde的一些东西大家可以下下看啊(matlabde some things we can look at under ah ha ha)

this code optimize the parameter of PID controller

The attached file provides information to those interested in learning matlab.

该程序为BPSK调制的MATLAB源代码，首先通过仿真得到信号源，再进行调制(The program for the BPSK modulation MATLAB source code, first get the signal source through simulation, then modulate)

基于mathematica的数学微分实验书籍，包括mathematica的基本教程和实验源码(Basic tutorials and source-based experimental math mathematica differential experiment books, including the mathematica)

fuelcell model燃料电池模型，可直接套用。(fuel cell model_files)

扩展卡尔曼滤波工具箱，里面包含了多种滤波方法和详细的例子，是学习的好工具(Extended Kalman filter kit, which contains a variety of filtering methods and a detailed example is a good tool for learning)

说明：  自相关函数和互相关函数的matlab计算和作图，这个是信号分析里的概念，他们分别表示的是两个时间序列之间和同一个时间序列在任意两个不同时刻的取值之间的相关程度。(Self correlation function and cross-correlation function of matlab calculation and drawing, this is a concept in signal analysis, they are respectively represent the is between any two different time value relevance of the two time series and the same time series.)

the code for four bit qpsk with 90 degrees phase shift with constellation and without constellation of noise is given
