Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length
, 2017 In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...

Encoding of QC-LDPC Codes of Rank Deficient Parity Matrix
Journal of Engineering, 2016 the encoding of long low density parity check (LDPC) codes presents a challenge compared to its decoding. The Quasi Cyclic (QC) LDPC codes offer the advantage for reducing the complexity for both encoding and decoding due to its QC structure.

New decoding scheme for LDPC codes based on simple product code structure
, 2012 In this paper, a new decoding scheme for low-density parity-check (LDPC) codes using the concept of simple product code structure is proposed based on combining two independently received soft-decision data for the same codeword.
