An Upper Bound on the Minimum Distance of LDPC Codes over GF(q)
, 2015 In [1] a syndrome counting based upper bound on the minimum distance of regular binary LDPC codes is given. In this paper we extend the bound to the case of irregular and generalized LDPC codes over GF(q). The comparison to the lower bound for LDPC codes

Performance Analysis and Design of Two Edge Type LDPC Codes for the BEC Wiretap Channel
, 2011 We consider transmission over a wiretap channel where both the main channel and the wiretapper's channel are Binary Erasure Channels (BEC). We propose a code construction method using two edge type LDPC codes based on the coset encoding scheme.

Decoding Optimization for 5G LDPC Codes by Machine Learning
IEEE Access, 2018 In this paper, we propose a generalized minimum-sum decoding algorithm using a linear approximation (LAMS) for protograph-based low-density parity-check (PB-LDPC) codes with quasi-cyclic (QC) structures.

Tanner
IEEE Access, 2019 Girth plays an important role in the design of low-density parity-check (LDPC) codes. Motivated by the works on the girth of some classes of Tanner quasi-cyclic (QC) LDPC codes, e.g., Tanner (3, 5), (3, 7), (3, 11), and (5, 7) codes, we, in this paper ...

Comparison of LDPC block and LDPC convolutional codes based on their decoding latency
2012 7th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2012 We compare LDPC block and LDPC convolutional codes with respect to their decoding performance under low decoding latencies. Protograph based regular LDPC codes are considered with rather small lifting factors. LDPC block and convolutional codes are decoded using belief propagation.

Short Block-length Codes for Ultra-Reliable Low-Latency Communications
, 2018 This paper reviews the state of the art channel coding techniques for ultra-reliable low latency communication (URLLC). The stringent requirements of URLLC services, such as ultra-high reliability and low latency, have made it the most challenging ...
