Research Themes

Theory of adaptive signal processing and Its application

I am studying an adaptive filter theory and its applications whose characteristics have better properties against noisy signals than the conventional RLS method. The proposed algorithm has better performance in the worst case with the same computational complexity as the conventional method.
