Actions as Space-Time Shapes
Human action in video sequences can be seen as silhouettes of a moving torso and protruding limbs undergoing articulated motion. We regard human actions as three-dimensional shapes...

Learning a Hierarchy of Discriminative Space-Time Neighborhood Features for Human Action Recognition
Recent work shows how to use local spatio-temporal features to learn models of realistic human actions from video. However, existing methods typically rely on a predefined spatial...

Asymptotic Analysis of Space-Time Codes in Non-Gaussian Noise and Interference
— In this paper, we provide a framework for the asymptotic performance analysis of space–time codes (STCs) in correlated Ricean fading and non–Gaussian noise and interference...

Optimal Precoder for Rate 1 Space-Time Block Codes
Abstract— Despite primary space-time coding where the channel state information (CSI) is available at the receiver only, the capacity and performance of multiple-input multiple-o...

Precoding for Multiuser Orthogonal Space-Time Block-Coded OFDM: Mean or Covariance Feedback?
Abstract— This paper presents precoding design for errorrate improvement in closed-loop multiuser orthogonal space-time block-coded (OSTBC) multiple-input multiple-output (MIMO) ...
