Abstract
It is shown that an adaptive echo canceller with asynchronous inputs affected by sampling time jitter can be modeled as the identification of a time-varying channel by an adaptive filter, both the channel and the adaptive filter being fed with synchronous data. This allows application of theoretical results of the identification problem which are already known. It is proved that the problem is similar when the transmitter itself is slaved on an external jittered clock and the echo canceller is synchronous. >Keywords
