Unformatted text preview: Recursion for norm: Initialization: GAL Filters GAL Filters Normalized step-size tracks variations in environment: Prediction errors are the cue for adaptation. Prediction errors small : E m-1 [n] small and m [n] large in magnitude, i.e, fast adaptation mode. Noisy environments: E m-1 [n] large and m [n] smaller in magnitude, i.e, noise rejection mode. GAL Filters GAL Filters Superior to the LMS : lower noise sensitivity of m [n] and better tracking capabilities via m [n]. Computationally simple and attractive for practical implementation. Convergence of GAL inferior to RLS-based lattice structures....
