Low-Complexity Data-Reuse RLS Algorithm for Stereophonic Acoustic Echo Cancellation

Low-Complexity Data-Reuse RLS Algorithm for Stereophonic Acoustic Echo Cancellation

Stereophonic audio devices employ two loudspeakers and two microphones in order to create a bidirectional sound effect. In this context, the stereophonic acoustic echo cancellation (SAEC) setup requires the estimation of four echo paths, each one corresponding to a loudspeaker-to-microphone pair. Th...
