Abstract
The fast convergence rate and its immunity to the eigenvalue spread of the input correlation matrix make the RLS algorithm particularly attractive. Ho wever, the computational complexity Is high, In this letter, we propose usi ng a hierarchical approach to reduce the computational complexity and furth er increase the convergence rate. The results of simulation runs and theore tical justifications confirm our claims.
