Abstract
The authors introduce a frequency-domain adaptive filter (FDAF) configuration using the overlap-add method which has the same complexity and convergence behavior as the overlap-save configuration. It is shown that an FDAF using the overlap-add method can be realized with the same number of DFTs (discrete Fourier transforms) as the FDAF using the overlap-save method. The overlap-add implementation of an FDAF with seven DFTs is described.<>
