摘要：

A straightforward generalization of the so-called affine projection algorithm (APA) to the multichannel (MC) case is easily obtained. However, due to the strong correlation between the input signals of the various channels, the resulting algorithm converges very slowly. This letter describes the way to overcome this problem and derives an efficient algorithm that turns out to make use of additional orthogonal projections.
