Microphone array signal processing for robot audition [PDF]

2017 Hands-free Speech Communications and Microphone Arrays (HSCMA), 2017
Robot audition for humanoid robots interacting naturally with humans in an unconstrained real-world environment is a hitherto unsolved challenge. The recorded microphone signals are usually distorted by background and interfering noise sources (speakers) as well as room reverberation.

Phased-MIMO Radar: A Tradeoff Between Phased-Array and MIMO Radars [PDF]

, 2009
We propose a new technique for multiple-input multiple-output (MIMO) radar with colocated antennas which we call phased-MIMO radar. The new technique enjoys the advantages of MIMO radar without sacrificing the main advantage of phased-array radar which ...
