On the transfer matrix of a MIMO system
Francois Bentosela, Horia D. Cornean, Bernard Fleury +1
We develop a deterministic ab-initio model for the input-output relationship of a multiple-input multiple-output (MIMO) wireless channel, starting from the Maxwell equations combin…
On the Role of Feedback in LT Codes
Jesper H. Sørensen, Petar Popovski, Jan Østergaard
This paper concerns application of feedback in LT codes. The considered type of feedback is acknowledgments, where information on which symbols have been decoded is given to the tr…
n-Channel Asymmetric Entropy-Constrained Multiple-Description Lattice Vector Quantization
Jan Ostergaard, Richard Heusdens, Jesper Jensen
This paper is about the design and analysis of an index-assignment (IA) based multiple-description coding scheme for the n-channel asymmetric case. We use entropy constrained latti…
Coordinated Transmissions to Direct and Relayed Users in Wireless Cellular Systems
Chan Dai Truyen Thai, Petar Popovski, Megumi Kaneko +1
The ideas of wireless network coding at the physical layer promise high throughput gains in wireless systems with relays and multi-way traffic flows. This gain can be ascribed to t…
Design and Analysis of LT Codes with Decreasing Ripple Size
Jesper H. Sørensen, Petar Popovski, Jan Østergaard
In this paper we propose a new design of LT codes, which decreases the amount of necessary overhead in comparison to existing designs. The design focuses on a parameter of the LT d…
Bounding the Rate Region of Vector Gaussian Multiple Descriptions with Individual and Central Receivers
Guoqiang Zhang, W. Bastiaan Kleijn, Jan Østergaard
In this work, the rate region of the vector Gaussian multiple description problem with individual and central quadratic distortion constraints is studied. In particular, an outer b…
