Fixed-point Implementation of a Coherence-based Double-talk Detector for Line Echo Cancelers
نویسنده
چکیده
In this paper we justify the need and describe the implementation of a spectral coherence based double-talk detector for line echo cancelers on a 16 bit signal processor. We address specific fixed-point implementation issues and we illustrate the superiority of the solution over the energy/level based Geigel detector, along with a discussion about the use cases.

Coherence Based Double Talk Detector with Adaptive Threshold
Acoustic echo cancellation is one of the oldest applications of the adaptive filters and today part of each speakerphone. An important block of each acoustic echo canceller is the double talk detector. It blocks the adaptation of the filter when near end voice is present and thus preventing the adaptive filter from diverging from the optimal position. In this paper we present an improved versio...
متن کاملEnhanced Double-talk Detection Based on Pseudo-coherence in Stereo
ABSTRACT This paper aims at double-talk detection for acoustic echo cancellers enabling transmission of speech signals in stereo. Double-talk detectors are affected by the same known non-uniqueness problem as echo cancellers. However, echo cancellers are usually adapted using NLMS-like iterative algorithms. Double-talk detectors being based on pseudo-coherence employ traditional spectral estima...
متن کاملOn integrating acoustic echo and noise cancellation systems for hands-free telephony
An integrated acoustic echo and noise cancellation system for hands-free telephony is presented. The proposed system includes a new residual echo cancellation scheme based on spectral analysis and a new double-talk detector suitable for real-time implementation. Residual echo is whitened via AR analysis during no near-end-talk period and is cancelled by noise reduction. Removing speech characte...
متن کاملDesign and Implementation on a Sub-band based Acoustic Echo Cancellation Approach
This paper describes the design and implementation of a sub-band based acoustic echo cancellation approach, which incorporates the normalized least mean square algorithm and the double talk detection algorithm. According to the simulation, the proposed approach works well in the modest linear noisy environment. Since the proposed approach is implemented in fixpointed C, it can be easily ported ...
متن کاملA frequency-domain double-talk detector based on a normalized cross-correlation vector
A key component for hands-free, full-duplex, communication technology is the echo canceler. An echo canceler consists primarily of an adaptive 4lter and a control device called the double-talk detector. We derive a test statistic based on a normalized cross-correlation vector for the multichannel frequency-domain adaptive algorithm. The advantages of this approach are: low computational complex...
