Abstract
This paper presents a new integrated acoustic echo and noise canceller for hands-free communications that includes computationally efficient double-talk detection, residual echo cancellation, and IS-127 noise reduction. The proposed system was implemented in real-time using a 16-bit fixed-point DSP
