摘要
Spectral estimation method is an effective method in the case of parameter estimation of sinusoid signal in noises.It always applies cross spectral estimation theory and high order self spectral estimation methods up to now.Yule Walker equation based on cross fourth order cumulant is developed and Pisarenko method is provided in this paper.Simulation results show that the method is effective to retrieve sinusoid signal frequencies from hybrid colored noises and has good performance.
Spectral estimation method is an effective method in the case of parameter estimation of sinusoid signal in noises. It always applies cross-spectral estimation theory and high-order self-spectral estimation methods up to now. Yule-Walker equation based on cross-fourth-order cumulant is developed and Pisarenko method is provided in this paper. Simulation results show that the method is effective to retrieve sinusoid signal frequencies from hybrid colored noises and has good performance.
