| 摘 要： | 数字通信调制方式识别一直是信号截获处理方面的热点课题,是信号筛选和解调的基础,在通信对抗中意义重大。本文提出了以接收信号的四、六阶累量为特征来识别数字调制信号,文中进行了理论推导,并做了仿真验证该方法的可行性,实现了对2A SK/2PSK、4A SK、8A SK、4PSK、8PSK、16SQAM等数字调制类型识别。

| Abstract: | The modulation recognition of digital communication is the foundation of selecting signals and signal demodulation and a still hot problem in the intercepted signal processing.It plays an important role in communication countermeasure and develops good condition for further signal processing.This paper proposes a new method based on received signal of fourth and sixth order cumulants for classification digital modulation signals.The method is illuminated and verified.Using computer simulation,recognition of the 2ASK/2PSK,4ASK,8ASK,4PSK,8PSK and 16SQAM signals is efficient. |
