A Distortion Reducing Subband Limiter Implementation for Conference Phones
Blekinge Institute of Technology, School of Engineering, Department of Signal Processing2008 (English)Conference paper (Refereed) Published
Distortion, most often caused by the loudspeaker, is a practical problem in acoustic echo cancellation-based conference phones. Typically, this distortion varies significantly with the frequency. This paper presents an implementation of a distortion reducing subband limiter to be used in conjunction with an acoustic echo canceller in a commercial conference phone, yielding improved cancellation performance. Verification of the performance was performed through evaluation of a fix-point real-time implementation.
