Polar codes for distributed hierarchical source coding
Hierarchical source coding, also known as successive refinement of information, was introduced by Koshelev [1,2] and Equitz and Cover [3]. This problem is concerned with the construction of a source code for a discrete memoryless source X with respect to a given distortion measure d1 that can be further refined to represent the same source within another distortion measure d2 so that both repre...
متن کاملPolar Codes for Channel and Source Coding
Polar codes, introduced recently by Arıkan, are the first family of codes known to achieve capacity of symmetric channels using a low complexity successive cancellation decoder. Although these codes, combined with successive cancellation, are optimal in this respect, their finite-length performance is not record breaking. We discuss several techniques through which their finite-length performan...
متن کاملAn efficient secure channel coding scheme based on polar codes
In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
متن کاملRate-adaptive codes for distributed source coding
Source coding with correlated decoder side information is considered. We impose the practical constraint that the encoder be unaware of even the statistical dependencies between source and side information. Two classes of rate-adaptive distributed source codes, both based on Low-Density Parity-Check (LDPC) codes, are developed and their design is studied. Specific realizations are shown to be b...
متن کاملDistributed Source Coding using Abelian Group Codes
In this work, we consider a distributed source coding problem with a joint distortion criterion depending on the sources and the reconstruction. This includes as a special case the problem of computing a function of the sources to within some distortion and also the classic Slepian-Wolf problem [62], Berger-Tung problem [46], Wyner-Ziv problem [44], Yeung-Berger problem [47] and the Ahlswede-Ko...
