Augmented LT codes over binary extension fields with increased ratio of full‐degree columns
Electronics LettersThis letter proposes an augmented scheme of LT codes to improve the decoding success rate. The method involves substituting the 1‐s in full‐degree columns of the generator matrix of conventional LT codes with binary extension field elements and ...

AONT-LT: a Data Protection Scheme for Cloud and Cooperative Storage Systems
, 2014 We propose a variant of the well-known AONT-RS scheme for dispersed storage systems. The novelty consists in replacing the Reed-Solomon code with rateless Luby transform codes.

Luby Transform Coding Aided Bit-Interleaved Coded Modulation for the Wireless Internet [PDF]
, 2007 Bit-Interleaved Coded Modulation using Iterative Decoding (BICM-ID) is amalgamated with Luby Transform (LT) coding. The resultant joint design of the physical and data link layer substantially improves the attainable Bit Error Rate (BER) performance.

Multilevel Decoders Surpassing Belief Propagation on the Binary Symmetric Channel
, 2011 In this paper, we propose a new class of quantized message-passing decoders for LDPC codes over the BSC. The messages take values (or levels) from a finite set.

Explicit construction of girth-eight QC-LDPC codes and its application in CRT method
Tongxin xuebao, 2012 For arbitrary code lengths of the form PL(P≥3L<sup>2</sup>/4+L-1),a new family of (4,L)-regular quasi-cyclic (QC) low-density parity-check (LDPC) codes was proposed explicitly with girth ight.Employing the new code as a component code in the ...

Analysis of the Second Moment of the LT Decoder
, 2009 We analyze the second moment of the ripple size during the LT decoding process and prove that the standard deviation of the ripple size for an LT-code with length $k$ is of the order of $\sqrt k.$ Together with a result by Karp et.

Bounds on the Reliability of RaptorQ Codes in the Finite-Length Regime
IEEE Access, 2017 In this paper we analyze the bounds on the reliability of RaptorQ codes under maximum likelihood decoding, especially in the finite-length regime. RaptorQ code ensembles by a high-order low density generator-matrix (LDGM) code as pre-code and an inner ...

Fountain Codes with Nonuniform Selection Distributions through Feedback
, 2015 One key requirement for fountain (rateless) coding schemes is to achieve a high intermediate symbol recovery rate. Recent coding schemes have incorporated the use of a feedback channel to improve intermediate performance of traditional rateless codes ...
