摘要
信号调制方式自动识别是非合作通信系统接收的重要课题;针对数字信号调制方式识别问题,采用一种基于特征参数直方图统计的自动识别算法,该算法计算量小,适于实时处理;计算机仿真结果表明:当信噪比大于18 dB时,正确识别率高于98%,具有良好的识别效果.
In both covert and overt operations, modulation identification plays an important role. In this paper, a set of algorithm for identifying different types of digital modulation is developed. Computer simulations for different types of band limited digitally modulated signals corrupted by band limited Gaussian noise have been carried out. It is found that implementation complexity of the algorithm is small and suitable for real time processing. All modulation types of interest have been classified with success rate ≥98% at SNR = 18 dB.
