摘　　要：通过理论及仿真分析,设计并验证了通过构造特征值判决识别信号调制模式。采用了六种常见模拟调制信号为样本进行识别区分测试,依据信号统计量和谱相关性的不同,采样并计算了四种特征参数;开展了信号特征识别算法验证及Matlab仿真实验;统计了算法识别率。结果表明:该判决方法可以在5～35 dB信噪比范围内对于信号调制模式进行高效准确的识别,具备较好的延展性,具有一定的实际参考意义。Through theoretical and simulation analysis,the decision signal modulation pattern is designed and verified by constructing eigenvalues.Six kinds of common analog modulation signals are used as samples for identification and discrimination test.According to the difference of signal statistics and spectral correlation,four characteristic parameters are sampled and calculated.The Matlab verification and simulation of signal feature recognition algorithm are carried out,and the recognition rate of the algorithm is accounted.The results show that the proposed method can recognize the modulation modes efficiently and accurately in the range of 5~35 dB signal-to-noise ratio.It has good extensibility and has a certain practical reference value.
