Title :
Normalised frequency-domain adaptive filter based on optimum block algorithm
Abstract :
A fast-convergence frequency-domain adaptive filter is described. A simple normalisation scheme in the frequency-domain optimum block algorithm (FOBA) is used to set the convergence factor separately in each frequency bin. This normalised FOBA (NFOBA) yields significant convergence improvements.
