Robust M-periodogram with dichotomous search

The problem of sinusoidal frequency estimation in heavy-tailed noise environment is addressed. A method based on the robust M -periodogram is proposed. Specifically, a suboptimal coarse frequency estimate provided by the robust M -periodogram is improved using the modified dichotomous search. Simulations that consider most common heavytailed noise models demonstrate that the proposed method outperforms several recently proposed methods. The method can be readily extended to deal with multiple sinusoids.
