Clap your hands! Calibrating spectral subtraction for dereverberation
Reverberation effects as observed by room microphones severely degrade the performance of automatic speech recognition systems. We investigate the use of dereverberation by spectr...

An Orthogonal Projection Approach for Blind Beamforming in Multipath CDMA Channels
In this paper, we propose a blind beamforming technique for multipath CDMA channels, which requires prior knowledge of only the spreading code and the timing of the desired user. ...

Analyzing the performance of error-prone relay networks
In this paper, we provide a semi-analytical method for predicting the upper and lower bound of the end-to-end mutual information for a relay network with practical codes and diffe...

Unscented transform with online distortion estimation for HMM adaptation
In this paper, we propose to improve our previously developed method for joint compensation of additive and convolutive distortions (JAC) applied to model adaptation. The improvem...
