摘要
Abstract
The available methods for high accuracy estimation of MPSK carrier frequency are not suitable for real-time processing because of great computation load.A new approach of real-time estimation is proposed.Based on DDC and two-stage DFT processing of nonlinear transformed signal,the spectral lines corresponding to carrier frequency can be estimated with high accuracy in real-time.The simulation verifies that the estimation accuracy of the new method is close to that of the direct DFT method.关键词
