  • Abstract
    This paper presents a combined implementation of echo suppression, noise reduction and comfort noise for loudspeaker phones, with the novelty being the concurrent use of the intrinsic parameters. The proposed algorithms are verified by evaluation of a fix-point real-time implementation.
