Combinatorial Orthogonal Beamforming for Joint Processing and Transmission.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Communications. Feb2014, Vol. 62 Issue 2, p625-637. 13p.
Abstract: Coordinated multiple point transmission (CoMP) technologies have recently been proposed to improve the performance of cell-edge users who suffer strong inter-cell interference. Nevertheless, as more transmitters get involved in cooperation, the complex...
A User Selection Algorithm Using Angle between Subspaces for Downlink MU-MIMO Systems.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Communications. Feb2014, Vol. 62 Issue 2, p616-624. 9p.
Abstract: One of major issues in the efficient use of radio resource for multiuser multiple-input/multiple-output (MU-MIMO) systems is the selection of users to achieve the maximum system throughput. The optimal user selection algorithm, which requires exhaustiv...
Statistical Personalization of Ventricular Fiber Orientation Using Shape Predictors.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Medical Imaging. Apr2014, Vol. 33 Issue 4, p882-890. 9p.
Abstract: This paper presents a predictive framework for the statistical personalization of ventricular fibers. To this end, the relationship between subject-specific geometry of the left (LV) and right ventricles (RV) and fiber orientation is learned statistica...
Optimal Viewing Angle Determination for Multiple Vessel Segments in Coronary Angiographic Image.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Nuclear Science. 6/10/2014 Part 2, Vol. 61 Issue 3, p1290-1303. 14p.
Abstract: Angiographic image is the perspective projection of the whole body from a 3D space to a 2D imaging plane, in which X-ray is used. As such, topological vasculature information has been lost. In 2D angiograms, foreshortening and overlapping are commonly ...
Cluster-Based Motion Estimation Algorithm With Low Memory and Bandwidth Requirements for H.264/AVC Scalable Extension.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Circuits & Systems for Video Technology. Jun2014, Vol. 24 Issue 6, p1016-1024. 9p.
Abstract: Memory bandwidth and on-chip memory requirements are critical issues in motion estimation (ME) implementations for video compression. The H.264/AVC scalable extension (SVC) provides variable frame rate and resolution video in a compressed digital seque...
Power Oscillation Damping Improvement by Adding Multiple Wind Farms to Wide-Area Coordinating Controls.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Power Systems. May2014, Vol. 29 Issue 3, p1356-1364. 9p.
Abstract: This paper examines the feasibility of coordinating variable-speed wind farms with other power system devices, such as flexible ac transmission systems and synchronous generators, to damp low-frequency oscillations. For this purpose, an observer-based ...
A General Energy Barrier Model for Switching of Exchange Spring Media in an External Field.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Magnetics. Mar2014 Part 1, Vol. 50 Issue 3, p56-61. 6p.
Abstract: In this paper, a general energy expression is developed for a cluster of multilayer exchange spring media grains. We expand the rotation of the magnetization vectors to second order in elements of an exponential unitary transformation. The first and se...
Forest Sparsity for Multi-Channel Compressive Sensing.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Signal Processing. Jun2014, Vol. 62 Issue 11, p2803-2813. 11p.
Abstract: In this paper, we investigate a new compressive sensing model for multi-channel sparse data where each channel can be represented as a hierarchical tree and different channels are highly correlated. Therefore, the full data could follow the forest stru...
