Abstract | : | In the echo cancellation, the double-talk situation when both the near-end signal and far-end signal are presented degrades the performance of echo cancellation using the LMS algorithm or the NLMS algorithm. The ECLMS algorithm has been proposed to solve the double-talk problem. The characteristics of the ECLMS algorithm is using the correlation function of the input signal itself. On the other hand, the lattice structure has a attractive characteristics that the backward residuals are orthogonal to each other. The purpose of this paper is to derive an Orthognal-ECLMS algorithm utilizing the backward residuals of lattice structure. |
