| 摘 要： | 正交频分复用（OFDM）技术广泛应用于军用和民用领域。在通信侦察、信息对抗以及无线频谱监控等应用中,通常不能事先获得通信方的调制方式信息,这就需要对接收信号进行分析识别,以提取调制方式。在研究OFDM信号分选识别的基础上,重点研究了基于聚类的子载波调制方式识别方法。

| Abstract: | OFDM(orthogonal frequency division multiplexing) technology is widely applied in both civil and military fields.Meanwhile,in the range of communication reconnaissance,information countermine and wireless spectrum surveillance,The communicating clients′ modulation type usually can not be obtained in advance.Based on the demand of analyzing and recognizing received signals in order to acquire modulation,the OFDM identification is presented,and then the sub-carrier modulation recognition based on clustering is emphasized,which gives technique support to signal reconnaissance as well. |
