Abstract
In this paper we present novel solutions for microphone array speech enhancement systems that intelligently use the multipath environment to enhance signal coming from a desired location. We obtain a statistical principle that explains previously known factorization results of optimal beamformers, and proves a similar factorization holds for other new optimal estimators. Our solution requires a low computational load, and can be deployed on most of the platforms. We present speech recognition rates on real data, and compare a stereo versus a mono solution on this database.
