Abstract:

Aiming at the carrier frequency recovery problem of MPSK signals,we propose a carrier frequency fast estimation algorithm by combining spectral detection theory and nonlinear transformation in this paper.The algorithm theory is introduced in detail,and the algorithm performance simulation is given.The results show that the proposed algorithm can achieve the aim to estimate MPSK carrier frequency quickly and accurately.
