Analysis of Absorbing Sets for Array-Based LDPC Codes
— Low density parity check codes (LDPC) are known to perform very well under iterative decoding. However, these codes also exhibit a change in the slope of the bit error rate (BE...

Low-Complexity LDPC Codes with Near-Optimum Performance over the BEC
Recent works showed how low-density parity-check (LDPC) erasure correcting codes, under maximum likelihood (ML) decoding, are capable of tightly approaching the performance of an i...

Design and performance of a novel low-density parity-check code for distributed video coding
Low-density parity-check (LDPC) codes are nowadays one of the hottest topics in coding theory, notably due to their advantages in terms of bit error rate performance and low compl...

Long Length LDPC Code Construction and the Corresponding Decoder Implementation with Adjustable Parallelism
—In this paper, we propose a class of implementation friendly structured LDPC codes with low error floors. The proposed codes exhibit no apparent error floors as compared with qu...

Controlling LDPC Absorbing Sets via the Null Space of the Cycle Consistency Matrix
— This paper focuses on controlling absorbing sets for a class of regular LDPC codes, known as separable, circulantbased (SCB) codes. For a specified circulant matrix, SCB codes...
