摘要
通信信号调制方式自动识别是信号分析领域中一个比较新的研究方向,是未来软件无线电必须具备的功能之一。本文分别研究了对模拟调制信号的自动识别、数字调制信号的自动识别和模拟数字调制信号的联合自动识别,并且利用神经网络对特征参数进行简约处理,通过计算机仿真,能够达到较好的自动识别效果。
Automatic modulation recognition of communication signals is the signal analysis is a new research direction in the field, is one of the future must have the functions of software radio. The automatic identification of digital modulation signal automatic identification and simulation were studied in this paper, automatic identification of digital modulation signal to analog modulation signal, and the use of neural network with the feature parameters of the simple processing, through computer simulation, can achieve the automatic recognition effect is good.
