Abstract

In this paper, we propose a novel variable step-size algorithm for the adaptive lattice form structure filter for the echo canceller in telephone network. By the proposed techniques, it is demonstrated that the proposed algorithm yields the performances over the previous one. Computer simulation results in terms of Echo Return Loss Enhancement (ERLE) are provided to confirm the performances of the proposed algorithm. ©ICROS.
