| 摘 要： | 提出了一种基于反相对称调制（PISM）法的PIS—QPSK调制解调系统模型。该模型采用匹配滤波器进行接收，在QPSK的同相和正交支路上分别进行PISM调制解调。文中阐明了该系统的工作原理，并对其抗噪声性能进行了理论分析和仿真实验，得出PIS—QPSK系统具有抗强特定噪声的结论。

| Abstract: | This paper gave a PIS-QPSK modem system model based on Phase-Inversion Symmetric Modulation(PISM).The model receives by matching filter and performs PISM in cophase branch and orthogonal branch.After illuminating the model's operating principle,the paper made a mathematics analysis and emulation experiment on the system's antinoise performance.At last,a result that PIS-QPSK has superiority under the specific noise's condition was made. |
