摘要

研究基于决策理论算法的单载波多载波无线数字调制信号的特征参数提取与自动识别技术，提出了适合单载波多载波数字调制识别的决策分类器及相应识别步骤。在瞬时相位提取时，首次采用去相位折叠算法纠正相位折叠的影响，提高了特征参数的准确性。仿真结果表明，该方法取得较好的识别效果，且系统易于实现，在信号识别中具有广泛的应用前景。

Abstract

The characteristic parameter extraction and automatic identification technology of wireless digital signal modulated by single carrier and multicarrier based on decision theory algorithm are researched mainly and then the decision classifier

the identification steps corresponding which suitable for single carrier and multicarrier digital modulation recognition are put forward.A phase folding algorithm to correct the influence of phase folding was first used in instantaneous phase extraction and the accuracy of characteristic parameters was improved. The simulation results show it has good recognition effect

the system is easy to realize and it has a broad prospect of application in the signal recognition.
