Abstract
A straightforward generalization of the so-called affine projection al gorithm (APA) to the multichannel (MC) case is easily obtained. Howeve r, due to the strong correlation between the input signals of the vari ous channels, the resulting algorithm converges very slowly. This lett er describes the way to overcome this problem and derives an efficient algorithm that turns out to make use of additional orthogonal project ions.
