Engineering with departmental honors. He went on to Brown University in Providence, Rhode Island to study signal processing and began research on microphone arrays. He received a Master of Science degree in Electrical Engineering in 1993 and continued to pursue his work towards a Doctor of Philosophy degree. While a student at Brown, he held several(More)
A frequency-domain delay estimator has been used as the basis of a microphone-array talker location and beamforming system [Brandstein, M.S., and Silverman, H.F., Technical Report LEMS116, (1993)] . While the estimator has advantages over previously employed correlation-based delay estimation methods [Silverman, H.F. and Kirtman, S.E., Computer Speech and(More)
A major problem for speech recognition systems is relieving the talker of the need to use a close-talking, head-mounted or a deskstand microphone. A likely solution is the use of an array of microphones that can steer itself to the talker and can use a beamforming algorithm to overcome the reduced signal-to-noise ratio due to room acoustics.

The probabilistic data association filter (PDAF) is a consistent estimator for tracking Gaussian targets in clutter [1]. The algorithm works well in many different applications and is regarded by many to be the baseline for tracking a target in clutter [2—6]. Prominent among the desirable properties of PDAF is the fact that the track estimates are obtained(More)
