Orthogonal ECLMS algorithm for double-talk echo cancelling
In order to solve the double-talk problem in the echo cancelling for teleconference system, the authors have proposed the extended correlation least mean squares (ECLMS) algorithm. However, this algorithm does not give a fast convergence. The purpose of this paper is to derive an orthogonal ECLMS (OECLMS) with the lattice structure in order to speed up the convergence characteristics and to reduce the computational load for the adaptation.
