说明：  自相关的matlab程序。可以用于信号的周期性监测。(Since the procedures related to matlab. The cyclical nature of the signal can be used for monitoring.)

QPSK发送机，信号源为随机二进制序列，经串并变换后，转换成双极性信号发送(QPSK transmitter, the signal source for random binary sequence, series and transform, change the polarity signal sent in pairs)

自适应步长的Runge-Kutta-Fehlberg法解初问题常微分刚性方程组(Adaptive step size Runge-Kutta-Fehlberg method for solving initial problem of ordinary differential equations)

将要分析的数据放在C盘的ELI.xls表的Bay表单中，根据数据多少调整读取范围（修改 b2:f16 此句) 结果有两种，一种是按数据计算权值求出的结果，另一种是参考建议值求出的结果。结果写入C盘的ELI表格，范围要手动根据数据多少调整(The data will be analyzed on the C disk ELI.xls Table Bay form, how much to adjust the data read range (change ' b2: f16' sentence) result, there are two, one is calculated according to weight data the results obtained, the other is the result of reference to find the recommended value. Results written to C drive of the ELI forms, the scope of how much to manually adjust the data)

说明：  现代普估计的AR模型求解，采用的是周期图法，自己写的程序，菜鸟，谅解(AR model)

小波变换已应用到工程的各个方面，但一般只是应用MATLAB的小波工具包来编程，有时需要自己编程实现，故这里给出了DB4小波变换的C实现(Wavelet transform has been applied to all aspects of the project, but generally only apply MATLAB wavelet toolkit for programming, sometimes need their own programming, so here is a DB4 wavelet transform C implementation)

rs（255，239）码基于matlab编码，c语言译码，仿真性能优异(rs encoding with matlab,and decoding with c)

超宽带定位系统，较好的一本书，涉及很多方面的内容(Ultra-wideband positioning system, a good book, involving many aspects)
