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…
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…
