Semiunitary Precoding for Spatially Correlated MIMO Channels
— The focus of this paper is on spatial precoding in correlated multi-antenna channels where the number of datastreams is adapted independent of the number of transmit antennas. ...

Investigation of acoustic units for LVCSR systems
One important issue in designing state-of-the-art LVCSR systems is the choice of acoustic units. Context dependent (CD) phones remain the dominant form of acoustic units. They can...
