大气波导下，电磁波射频追踪研究，利用Matlab进行仿真(Radio Frequency Tracking of Electromagnetic Waves in Atmospheric Waveguide)

分析瑞利衰落信道下qpsk的snr与ber的关系(The relationship between QPSK SNR and ber in Rayleigh fading channel is analyzed)

说明：  bergeron仿真贝吉龙过程，温度低于0℃且过冷却水滴、冰晶、水汽共存的云区，由于冰面的饱和水汽压低，而水面的饱和水汽压高，因此便会有这样的情况出现，即当云中的水汽压处于冰面和水面饱和值之间时，水汽在冰晶上凝华而使冰晶长 大，而水滴会不断蒸发变小或消失，形成冰晶“ 夺取”水滴的水分和原来云中水汽的冰水转化过程。(The saturated water vapor pressure of the bergeron surface is high, so there will be a situation where the water vapor in the cloud is between the ice surface and the saturation value of the water surface, the water vapor condenses on the ice crystals and causes the ice crystals to grow, and the water droplets will The evaporation continues to become smaller or disa)

说明：  可用于matlab等绘制中国地图，即开即用，十分方便(It can be used in Matlab to paint a beautiful China Map.)

说明：  人工蜂群算法优化无刷直流电机PID控制，并采用三种评价指标函数IAE、ITAE、ITSE来进行对比分析(PID control of BLDCM is optimized by artificial bee colony algorithm, and three evaluation index functions IAE, ITAE and itse are used for comparative analysis)

一本LabVIEW书,可做为一本学LabVIEW入门的书和具有一定经验人的参考资料。(LabVIEW a book, can be used as a study of the book Introduction to LabVIEW and have some experience of the reference person.)

一个关于蜂窝小区和微小区的信道模型的MATLAB例子，很好用。(MATLAB example of a cell and microcell channel model, well used.)

本程序代码包含了 SC SCL BP SCAN和SSC译码算法，以及各种编码算法GA，BA....*** 编程语言风格为C++，研究polar的和我一样渣渣的研一萌新点进来have a look 感谢大佬pan jianpeng ，感谢共享源码(This program code includes SC SCL BP SCAN and SCC decoding algorithm, as well as various coding algorithms GA, BA... *** Programming language style is C++, research polar and slag like me have a look Thank you pan jianpeng, thank you for sharing the source code)

说明：  针对非合作遥感影像坐标偏差问题，根据google earth球面距离算法，给予自动修正。(For non-cooperation in remote sensing image coordinates of deviation, according to google earth spherical distance algorithm to give automatic correction.)

duffing 算子的仿真算法。 改变程序参数即可得到不同状态下的图形。(duffing operator simulation algorithm. Process parameters change under different conditions can be obtained graphics.)
