Self Reliability based Weighted Bit-Flipping Decoding for Low-density Parity-check Codes

Low Density Parity Check (LDPC) codes can be decoded in various ways, namely the Bit-Flipping (BF) algorithm, the Weighted BF algorithm (WBF), the Belief Propagation (BP) algorithm and so on. These algorithms provide a wide range of tradeoffs among decoding complexity, decoding speed, and error rate performance. In this paper, a novel self-reliability-based weighted bit-flipping decoding scheme...

Designing LDPC codes using bit-filling

Bipartite graphs of bit nodes and parity check nodes arise as Tanner graphs corresponding to low density parity check codes. Given graph parameters such as the number of check nodes, the maximum check-degree, the bit-degree, and the girth, we consider the problem of constructing bipartite graphs with the largest number of bit nodes, that is, the highest rate. We propose a simple-to-implement he...

LDPC for QKD Reconciliation

—We present the Low Density Parity Check (LDPC) forward error correction algorithm adapted for the Quantum Key Distribution (QKD) protocol in a form readily applied by developers. A sparse parity check matrix is required for the LDPC algorithm and we suggest using some that have been defined by the IEEE and ETSI standards organizations for use in various communication protocols. We evaluate the...

Use of Parity Checks Inherent in LDPC Codes for Dominant Error Events Detection and k-Constraint Enforcement

In this paper, we propose to leverage the simple and explicit parity checks inherent in low-density parity-check (LDPC) codes to realize dominant error events detection without code rate penalty. This is enabled by enforcing a very weak constraint on LDPC code parity check matrix structure. Such a constraint can be readily satisfied by most structured LDPC codes ever studied in the open literat...

Architectures for Decoding of Structured Ldpc Codes Using the On- the –fly Computation Paradigm

Recent research efforts based on joint code-decoder design methodology have shown that it is possible to construct structured LDPC (Low Density Parity Check) codes without any performance degradation. An interesting new data independence property between the two classes of messages viz. check to bit and bit to check involved in decoding, is observed. This property is a result of the specific st...

Soft Bit Decoding of Low Density Parity Check Codes

A novel soft-bit-domain decoding algorithm for low-density parity-check codes is derived as an alternative to belief propagation and min-sum algorithms. A simple approximation analogous to the min-sum approximation is also presented. Simulation results demonstrating the functionality of the algorithm are given both for floating and fixed point representations.
