摘要
研究通信信号调制方式和准确识别技术问题,是信号处理中的关键技术,并在军事和民用领域具有重要的作用,特征参数的调制方式识别方法主要分为特征参数提取和分类识别两个部分。在特征参数的调制识别方法的基础上,针对BPSK信号的特点,采用上述方法对BPSK信号进行调制识别,并在不同参数条件下通过仿真验证方法的有效性。仿真结果表明,特征参数的调制方式识别方法能在不同参数条件下准确识别出BPSK信号,提高了低信噪比条件下BPSK信号的识别准确率。
As the key technology of signal processing, the modulation recognition method based on characteristic parameters of communication signals is widely applied in civil and military area. The recognition method based on characteristic parameters is consisted of extracting characteristic parameters and classification. The recognition method based on characteristic parameters was used in this paper to recognize BPSK signals basing on the characteristics of BPSK signals and studying the theory of recognition method based on characteristic parameters. And the validity of this method was validated in different parameter conditions through simulating. The simulation results show that the recognition method based on characteristic parameters can recognize BPSK signals correctly. And this method can in- crease the recognition correctness of BPSK signals in the condition of low SNR.
