基于决策理论的软件无线信号调制样式自动识别

Study of the Automatic Idaltification of the Software Wireless Signal Modulation Style Based on Decision Theory

信号调制样式的自动识别是软件无线电台必须具备的功能之一.主要讨论了基于决策理论的信号调制样式自动识别的基本原理和算法,论述了模拟信号调制样式的自动识别,数字信号调制样式的自动识别方法.也分析了在实现这些算法时会碰到的许多具体的实际问题,提出了能解决这些问题的调制识别新方法——人工神经网络识别法.

The automatic identification of signal modulation style is an essential function of the wireless broadcasting station. This paper studies the theory and algorithm of the automatic identification of signal modulation style based on decision theory, discusses the automatic identification of analog digital signal modulation styles, analyses the practical problems during carrying out these algorithms, and provides a new modulation identification method artificial neural net identification to solve these problens.
