Multiple Description Coding for Stationary Gaussian Sources Academic Article uri icon

abstract

  • We consider the problem of multiple description coding for stationary Gaussian sources under the squared error distortion measure. The rate region is characterized for the 2-description case. It is shown that each supporting line of the rate region is achievable with a transform lattice quantization scheme. We show the optimal coding scheme has a natural spectral domain coding interpretation, which yields a reverse water-filling solution with a frequency-dependent water level instead of the flat water level as in the conventional single description case. 2009 IEEE.
