Cumulant-Based Approach to the Harmonic Retrieval
累量域谐波恢复方法(英文)

In order for cumulant based approach to be applied to harmonic retrieval and practical dynamic data, the topics of determinate initial phase, multi harmonic and wide dynamic range are studied, some new characteristics are obtained, and the defects of harmonic retrieval and noise pre filtering algorithms are pointed out. Finally, the improved algorithm for wide dynamic range signal is given. The simulation results show that the algorithm is effective and satisfactory.
