摘要
自动调制方式识别应用范围广泛,对于军用软件无线电侦察接收机更具有十分重要的意义。本文提出了一种基于统计参数识别信号类型的新方法,在满足SNR≥10dB的条件下,可正确识别2ASK、M-AM、QAM、PSK、FSK等五种信号。仿真试验表明:计算简单,识别效果良好。
Automatic identification of the modulation type of a signal has found applications in many areas, especially important for military software radio interception receiver. This paper presents a new method to classify the type of a signal using statistical parameters, when SNR≥10dB, identification of Automatic classification of digital modulation signals using statistical parameters methods HU Yan-ping,LI Guang-sen,LI Gang,HUANGFU Kan (Electronic Science and Engineering School of NUDT, Changsha 410073, China) Abstract: Automatic identification of the modulation type of a signal has found applications in many areas, especially important for military software radio interception receiver. This paper presents a new method to classify the type of a signal using statistical parameters, when SNR≥10dB, identification of the 2ASK、M-AM、QAM、PSK and FSK signals is reliable. Emulation indicated that this method is efficient.
