On the use of a linear data model for parameter estimation of sinusoidal FM signals
Jihao Yin, Yun Hua, Wanlin Yang, Tianqi Chen · 2009
A linear data model is presented for multi-component sinusoidal frequency-modulated (FM) signals, based on the fact that a sinusoidal FM signal can be decomposed into a set of harmonic frequencies, with harmonic amplitudes given by Bessel functions of the first kind. And via several properties derived from the present data model, a novel method is proposed to estimate the parameters of the multi-component sinusoidal FM signals. The feasibility of the proposed method is demonstrated by simulation results.
