一道关于卫星导轨的数学建模代码；本人自己数学建模赛的源代码，共参加数学建模参考(A guide rail on the mathematical modeling of satellite code)

基于16APSK调制解调传输系统的仿真 16APSK调制技术有较高的数据传输速率，但是它的误码率也相对较高。(16APSK modem-based transmission system simulation 16APSK modulation technique for a higher data transfer rate, but its relatively high error rate.)

用Taylor展开法、平方法等解常微分方程，非常直观易懂，适合于初学者。(start with Taylor, Xie Ping method ordinary differential equations, very intuitive to understand and suitable for beginners.)

实际光源不是绝对的单色，包含一定的光谱宽度△λ。△λ范围内的每一种波长的光都生成各自一组干涉条纹，除零干涉级外，相互间均有位移，使条纹对比度下降。(The actual light source is not absolutely monochromatic, contain a certain spectral width △ λ. Each wavelength of light within the range △ λ generates a set of interference fringes each, in addition to the zero level outside interference, mutual displacement are so fringe contrast decreases.)

一个比较有意思的程序，运行可以播放卡农的音乐(A more interesting program run can play the music of Canon)

Device on off with eyes

各种chaos相图和相关时序图，比如logistic等(Various chaos phase diagram and related timing diagram，Such as logistic , etc.)

这个文件实现把matlab中的数据先输出给txt文件，再输入到access数据库中。(This file implements the to matlab data output to a txt file, and then enter the access database.)

信号进行FFT变换,可以选择多个洋点,(Signal FFT transform, you can choose a number of ocean points,)
