Analysis of noise reduction and dereverberation techniques based on microphone arrays with postfiltering
TL;DR: A theoretical analysis of noise reduction and dereverberation algorithms based on a microphone array combined with a Wiener postfilter shows an appreciable reduction of acoustic echo and localized noise is obtained and makes the whole system highly attractive for hands-free communication systems.

Performance of adaptive dereverberation techniques using directivity controlled arrays
TL;DR: It is demonstrated that the use of a directivity controlled array is a requirement to ensure a sufficient robustness of the whole system and that the dereverberation performed by the postfilter is limited and its main interest lies in a significant reduction of the acoustic echo even in the double talk case.
