Abstract :
Fast versions of the so-called affine projection algorithm are based upon a specific approximation which theoretically is valid only if no regularisation is applied. We derive a fast frequency domain version of affine projection that does not need this approximation. As shown, this can be used to implement regularisation by means of an exponentially windowed updating procedure
