Abstract : This paper addresses the problem of adaptive noise cancelling with low signal-distortion. The proposed canceller consists in adding an adaptive decoupling filter to the well-known crosstalk resistant adaptive noise canceller (CTRANC) while maintaining the benefits of the cross-coupled structure. It uses a new cross-coupled structure named decoupled CTRANC (DCTRANC) suitable for situations where the noise reference sensor is closely spaced relative to the primary one. This method is analyzed and results are given in voice communication context.
