Abstract

In this paper, I present a new echo canceller using the adaptive cascade system identification (CSI) method, which a system response is divided into several responses so that each response is adaptively estimated and combined. Especially, for a fickle response, the performance of echo canceller using this CSI scheme is increased and computation complexity is decreased. This proposed method is verified through simulation of echo canceller for digital subscriber line (DSL) application.
