Robust methods for time delay estimation in the presence of impulsive noise
Xinyu Ma, Chrysostomos L. Nikias · 2002
In this paper new methods for time delay and frequency delay estimation are introduced based on the theory of alpha-stable distributions. It is shown that these methods are robust for both Gaussian and non-Gaussian impulsive noise environments. Their improved performance is clearly demonstrated through analytical results and simulation experiments with both computer generated data and actual radar clutter data.
