Simultaneous data transmission in both directions (full-duplex) over two-wired circuits can be achieved using two-wire to four-wire hybrid couplers. Transmission signal leakage through the near-end hybrid (near-end echo) and transmission signal reflection by the far-end hybrid (far-end echo) ending up in its own receiver due to imperfect hybrid isolation can greatly affect the correct detection of data from the other ...
Hoshuyama, O. Acoustics, Speech and Signal Processing (ICASSP), 2012 IEEE International Conference on, 2012
This paper proposes a new dual microphone echo canceller (DMEC) for suppressing loud nonlinear echo common with hands-free talk on small terminals such as cellphones. The proposed DMEC has an adaptive null former whose nulls by the dual microphones focus on cancelling the nonlinear echo which can not be cancelled by ordinary linear echo canceller. To focus on the nonlinear ...

An echo canceller, which consists of a linear echo canceller and a non-linear echo suppressor, has been proposed for mobile phones. This approach provides an efficient nonlinear echo suppressor with low computational complexity. In this method, the non-linear echo is estimated in the frequency domain from the linear echo replica. A ratio of the non-linear echo and the linear echo ...

Acoustic echo cancellation is a desirable feature for small cellular handsets that have significant acoustic coupling from speaker to microphone. Current echo cancellation techniques prefer an echo canceller to be placed at the wireless handset. Since echo cancellation requires much processing power it is beneficial to move the echo canceller to the base station, where power consumption will not be ...

Acoustic echoes arise whenever there is acoustic coupling between a loudspeaker and a microphone. A traditional solution for eliminating the undesired echo signal is an acoustic echo canceler (AEC), which identifies the echo path between a loudspeaker and a microphone by means of an adaptive filter. The echo signal can be canceled successfully when the modeling filter approaches the true ...
