摘要 采用了频域平滑周期图法估计循环谱,选取信号的Sx+(0)截面谱中谱峰个数为特征,提出了一种调制信号识别算法,给出了信号识别流程图及步骤,并进行了计算机仿真实验。仿真结果显示,该识别算法对这几种调制信号的识别具有较高的识别精度。 By the method of frequency domain smoothing periodogram to estimate the cyclic spectrum,selecting the spectrum peak numbers of Sx^＋（0）cross-section spectrum of signal as the charter,this paper presents a modulated signal recognition algorithm,gives the flow chart and the procedure of the signal recognition,and offers the computer simulation test.The results show that the recognition algorithm has a higher recognizing precision to the modulated signals.
