空气分离精馏塔动态模拟，用最原始的定义精确给出空气各组分的理论含量。(Air Separation system Dynamic Simulation Program)

例子关于buck的仿真，里面有simulink文件和一个绘制buck输出功率与占空比关系的matlab源文件。(About buck simulation example, which has drawn buck simulink file and a relationship between output power and duty cycle of the matlab source files.)

papr to differenrt number of subcarrier: we put N = 256,512,1024 and show the output ofp ccdf with papr when we use QPSK modulation. The PAPR ratio is a measure of the dynamic range in OFDM signals. Thus high PAPR induces a high dynamic range which describes high variability in the signal range. complex data sequences are input to the IDFT of an OFDM transmitter then at the output of the IDFT, real and imaginary parts are obtained.
