Polar Codes for Distributed Hierarchical Source Coding
arXiv:1404.5501 · doi:10.3934/amc.2015.9.87
Abstract
We show that polar codes can be used to achieve the rate-distortion functions in the problem of hierarchical source coding also known as the successive refinement problem. We also analyze the distributed version of this problem, constructing a polar coding scheme that achieves the rate distortion functions for successive refinement with side information.
