Abstract In this work, we address the frequency estimation problem of a complex singletone embedded in the heavy-tailed noise. With the use of the linear prediction (LP) property
and l1-norm minimization, a robust frequency estimator is developed. Since the proposed
method employs the weighted l1-norm on the LP errors, it can be regarded as an extension
of the lp-generalized weighted linear predictor. Computer simulations are conducted in the
environment of α-stable noise, indicating the superiority of the proposed algorithm, in
terms of its robust to outliers and nearly optimal estimation performance. More >
