Abstract

This paper proposes a new subband echo canceller that almost fully whitens the received input by using the low-order projection algorithm, or the affine projection algorithm. Since the projection algorithm can fully whiten the received input of a small-tap adaptive filter with a relatively small projection order, the proposed subband projection echo canceller achieves nearly maximum convergence with a small projection order. By reflecting the frequency characteristics of the speech and of the echo path, it allows a different projection order to be chosen in different subbands. This gives the proposed method optimum cost performance, which is promising for implementation.
