自动调制识别是非合作通信系统接收机设计中的重要研究课题。本文提出了一种基于软件无线电架构的自动调制识别算法。该算法计算量小,适合于在线分析。本文对高斯噪声中通信信号的自动识别进行了计算机仿真。实验结果表明,在信嗓比为15dB时,识别成功率不低于98％。
Automatic modulation recognition is an important research topic in the receiver design of non-cooperative communication system. This paper presents an automatic modulation recognition algorithm based on software radio architecture. The algorithm has a small amount of computation and is suitable for online analysis. In this paper, automatic identification of communication signals in Gaussian noise is simulated by computer. The experimental results show that the recognition success rate is not less than 98% when the signal-to-speech ratio is 15dB.
