AM

基于镜像延拓法的emd分解，用于解决端点效应(EMD decomposition based on mirror extension method to solve endpoint effect.)

说明：  实现了8PSK的调制，画出了时域及频域信号波形，以及8PSK的星座图。(The 8PSK modulation is realized, and the time domain and frequency domain signal waveforms, as well as the 8PSK constellation diagram are drawn.)

GPS的CA码产生过程，对CA码进行bpsk调制后得到一个GPS中频信号，画出其时域和频域图(GPS-CA code generation process, the CA code bpsk modulated IF signal of a GPS, to draw the time-domain and frequency domain Figure)

说明：  MIMO系统由于在空间中具有多个发送和接收天线，因此其信道模型也具有其特有的复杂性。尽管具有这种复杂性，对MIMO信道进行建模仍然十分必要。(Because MIMO system has multiple transmit and receive antennas in space, its channel model also has its own complexity. Despite this complexity, it is still necessary to model MIMO channels.)

说明：  采用MATLAB语言生成的oam信号，可用于波动光学研究(OAM signal generated by MATLAB)

燃气轮机设计计算：采用理想工质，设计稳态工况下压气机、燃烧室、透平各截面热力参数的计算。 (Gas Turbine Performance Calculation, ideal gas working fluid, compressor performance calculations, Turbine performance calculations, ennergy balance for the combustion chamber.)

说明：  通过龙格库法计算步长，运动不同阻尼和弹簧隔振策略，对 振动进行控制分析。(The vibration is controlled and analyzed by calculating step length, different damping and spring vibration isolation strategies with rungeku method.)

说明：  多输入多输出系统的MATALAB仿真全部代码，可以运行。(Multiple-input multiple-output system simulation MATALAB all code can run.)

说明：  EEMD分解信号，可将信号分解为不同频率的固有模态分量，方便后续分析(EEMD decomposition signal)
