Challenges and some new directions in channel coding
(Korean Institute of Communication Sciences, 2015)Three areas of ongoing research in channel coding are surveyed, and recent developments are presented in each area: Spatially coupled low-density parity-check (LDPC) codes, nonbinary LDPC codes, and polar coding. -
Channel polarization: a method for constructing capacity-achieving codes for symmetric binary-input memoryless channels
(IEEE, 2009)A method is proposed, called channel polarization, to construct code sequences that achieve the symmetric capacity I(W) of any given binary-input discrete memoryless channel (B-DMC) W. The symmetric capacity is the highest ... -
A note on some inequalities used in channel polarization and polar coding
(Institute of Electrical and Electronics Engineers, 2018)We give a unified treatment of some inequalities that are used in the proofs of channel polarization theorems involving a binary-input discrete memoryless channel. -
On the origin of polar coding
(Institute of Electrical and Electronics Engineers Inc., 2016)Polar coding was conceived originally as a technique for boosting the cutoff rate of sequential decoding, along the lines of earlier schemes of Pinsker and Massey. The key idea in boosting the cutoff rate is to take a ... -
Polarization for arbitrary discrete memoryless channels
(IEEE, 2009)Channel polarization, originally proposed for binary-input channels, is generalized to arbitrary discrete memoryless channels. Specifically, it is shown that when the input alphabet size is a prime number, a similar ... -
Source polarization
(IEEE, 2010)The notion of source polarization is introduced and investigated. This complements the earlier work on channel polarization. An application to Slepian-Wolf coding is also considered. The paper is restricted to the case of ... -
Strange attractor in density evolution
(IEEE Computer Society, 2019)The strange attractor represents a complex pattern of behavior in dynamic systems. This paper introduces a strange attractor of channel polarization as a result of a geometric property of density evolution for code ... -
A survey of Reed-Muller codes from polar coding perspective
(IEEE, 2010-01)A survey of Reed-Muller (RM) coding is given with the goal of establishing a continuity between RM codes and polar codes. The focus is mainly on recursive decoding methods for RM codes and other ideas that are most relevant ...
