Abstract

Abstract A blind estimation method based on cyclic spectrum density is proposed to estimate carrier frequency and symbol rate with respect to non-cooperative communication. The cyclostationarity of modulated signals is used to estimate carrier frequency and symbol rate within frequency domain and cyclic frequency domain separately. Both theoretical analysis and simulation results show that the presented method is noise-insensitive and robust.
