A Combined Implementation of Echo Suppression, Noise Reduction and Comfort Noise in a Speaker Phone Application

• Echo suppression, noise reduction and comfort noise are desirable features in loudspeaker phone products. This paper proposes a set of algorithms for a combined, subband based, implementation of these three processing blocks. The proposed algorithms are verified by evaluation of a fix-point real-time implementation.
