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…
Colored-Gaussian Multiple Descriptions: Spectral and Time-Domain Forms
Jan Ostergaard, Yuval Kochman, Ram Zamir
It is well known that Shannon's rate-distortion function (RDF) in the colored quadratic Gaussian (QG) case can be parametrized via a single Lagrangian variable (the "water level" i…
Improved Upper Bounds to the Causal Quadratic Rate-Distortion Function for Gaussian Stationary Sources
Milan S. Derpich, Jan Østergaard
We improve the existing achievable rate regions for causal and for zero-delay source coding of stationary Gaussian sources under an average mean squared error (MSE) distortion meas…
