通信信号调制样式盲识别

Blind recognition of communication signal modulation

通信信号调制样式盲识别是信息获取的首要步骤,目前大多科研院所主要集中于识别算法及分类器的研究,识别过程复杂。提出采用图形化的信号显示界面,利用通信信号不同调制样式与各类信号显示图形的关联关系,直观展示通信信号的调制方式。这种方式易于上手,有较好的工程实践效果,且对于特种调制样式信号的识别也有很好的分析辅助效果。

Modulation recognition is the first step to obtain the message from the signal.Lots of research institutes are aiming at the research of recognition algorithm and classification now,but it＇s very complex.The signal＇s graphical display is put forward,which can realize the modulation recognition easily,based on the relationship between different modulation and different graphical content.This way is easy to be operated,and has agood effect in practice.It＇s also helpful to realize the special modulation signal for communication engineers.
