摘　　要：本文介绍了2DPSK调制解调的基本原理并在SystemView平台上构建了一个2DPSK调制解调系统的仿真模型。通过使用SystemView分析窗口观察信号的波形和频谱,我们能直接观测到信号在传输过程中的波形和频谱的变化,这有助于我们更深刻地理解2DPSK调制解调系统的工作原理和各个设备的功能。In the paper, we first introduce the basic principles of 2DPSK modulation and demodulation. Then, we build a 2DPSK modulation and demodulation simulation system on SystemView. By using the analytical window of SystemView to observe signal waveform and spectrum, we can see the changes of signal waveform and spectrum in signal transmission process directly, which helps us understand the working principle of 2DPSK modulation and demodulation system and functions of its devices more deeply.
