英文摘要	Aiming at the problem of carrier frequency failure of communication signal in Alpha stable noise environment, a method of carrier frequency estimation based on generalized cyclic spectrum was proposed. First, a generalized cyclic spectrum was defined by using non-linear transformation, and the signal amplitude was transformed. This non-linear transformation suppresses non-Gaussian impulse noise in communication signals. Since the generalized cyclic spectrum does not change the cyclic frequency of the cyclic spectrum, the spectral structure of the signal is consistent with the original signal structure. Carrier frequency estimation was achieved by detecting the relationship between the spectral position of the generalized cyclic spectrum and the carrier frequency of the digitally modulated signal. The simulation results and performance analysis of Matlab shows that this method can estimate the carrier frequency of communication signal in Alpha stable noise environment, and it has certain feasibility. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology.
