the file is the algorithm used for the color based seganography with multiple compression algorithms

通过Fourier与Laplace逆变换，把时域图变成频域图，增强信号的可视性。(Through the inverse transformation of Fourier and Laplace, the time domain diagram is transformed into frequency domain graph to enhance the visibility of the signal.)

《MATLAB语言与自动控制系统设计》pdf，很好的资料。(MATLAB language and the automatic control system design with the book resources, good information. )

滚降系数为0.5，载波频率fc=40/T.基带信号的频谱和幅度已调信号的频谱。(Roll-off factor of 0.5, the carrier frequency fc = 40/T. base-band signal spectrum and amplitude spectrum signals have been transferred.)

说明：  介绍SIMULINK的电子文档，很实用，内容很详细，对于利用SIMULINK搭建模型仿真的同学很实用(Introduction SIMULINK electronic documents, it is practical, the content is very detailed model for simulation using SIMULINK to build the students very practical)

说明：  南航写的gps仿真器源码，用matalb编写的一个比较简单的GPS仿真器，供大家学习和参考。(China Southern gps emulator written source, matalb prepared using a relatively simple GPS simulator for them to learn from and reference.)

对于任意三个整数，判断其是否为一个合法的日期值。给定一个日期值，计算若干天后的日期值，(For any three integers, determine whether it was a valid date value. Given a date and calculate the value of a number of days of the date,)
