摘　　要：在软件无线电的基础上,用软件LabVIEW的方式实现通信信号非实时的自动识别。调制制式的自动识别是非合作通信系统接收机设计的重要研究课题。利用特征参数研究了软件无线电中常用调制制式信号的自动识别,并基于决策树识别方案,对叠加了高斯白噪声的通信信号用LabVIEW编制了自动识别模块,仿真结果表明该算法具有较为理想的识别效果。This paper adopts software LabVIEW to realize the non-real-time automatic modulation recognition for communication signals based on the software radio. The automatic recognition to the modulation style is an important research topic of receiver design in non-cooperative communication system. This paper studies the automatic recognition to common modulation style signal in software radio by means of characteristic parameters, and establishes the automatic recognition module for the communication signals has been superimposed Gaussian white noise based on decision tree recognition project by LabVIEW. The simulation result shows that this recognition algorithm can obtain comparably perfect recognition effect.
