摘要
调制信号载频是调制样式识别中的基本参数,载频估计在调制样式识别中起着至关重要的作用。文章给出了三种载频估计方法,其中,谱相关估计法较传统的估计方法优点突出。
The carrier frequency of modulation signal is the basic parameter in the recognition of modulation type, and carrier frequency estimation plays an important role in the recognition of modulation type. This paper points out three methods for carrier frequency estimation, among them the cyclic spectrum correlation estimation method is much better than the traditional ones.
