In many applications with highly correlated input signals, the affine projection (AP) adaptive filter has good performance. However it is often too complex to implement in real time. In this paper, we describe an efficient implementation technique for the AP adaptive filter. For this technique, we derive the subband affine projection algorithm from the orthogonal analysis filter bank. And we apply the pipelining technique to the the derived subband adaptive filter for high processing speed.
