摘　　要：本文提出了一种基于信号瞬时幅度与小波分析相结合的数字调制制式的自动识别新算法。该算法计算简单、实时性强,能够成功识别2ASK、4ASK、2FSK、4FSK及2PSK5种信号。仿真结果表明,该算法具有较高的识别率。A new algorithm based on the combination of instantaneous amplitude of signal and wavelet transform is proposed for automatic identification of digital modulated signals. This algorithm is fcatured by simple computation and real time processing. The 2ASK,4ASK,2FSK,4FSK and 2PSK signals are classified successfully. Simulation results show the accuracy of the algorithm.
