Optimal Index Assignment for Multiple Description Scalar Quantization
Guoqiang Zhang, Janusz Klejsa, W. Bastiaan Kleijn
We provide a method for designing an optimal index assignment for scalar K-description coding. The method stems from a construction of translated scalar lattices, which provides a…

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…
