Although 4G (fourth generation) ie LTE (long term evolution) systems are now in use world-
wide. But today's 4G systems have some challenges left such as spectrum scarcity and …

Iterative decoders for finite length quantum low-density parity-check (QLDPC) codes are
attractive because their hardware complexity scales only linearly with the number of physical …

In this paper, we study the relationships between the girth of the Tanner graph of a quasi-
cyclic (QC) protograph low-density parity-check (LDPC) code, the lifting degree, and the size …

This paper is concerned with construction and structural analysis of both cyclic and quasi-
cyclic codes, particularly low-density parity-check (LDPC) codes. It consists of three parts …

This paper addresses the prediction of error floors of low-density parity-check codes
transmitted over the additive white Gaussian noise channel. Using a linear state-space …

In this paper, we study the cycle distribution of random low-density parity-check (LDPC)
codes, randomly constructed protograph-based LDPC codes, and random quasicyclic (QC) …

In this paper, we study the graphical structure of elementary trapping sets (ETSs) of variable-
regular low-density parity-check (LDPC) codes. ETSs are known to be the main cause of …

In this paper, we propose a new characterization for leafless elementary trapping sets
(LETSs) of variable-regular lowdensity parity-check codes. Recently, Karimi and …

Using easy-to-follow mathematics, this textbook provides comprehensive coverage of block
codes and techniques for reliable communications and data storage. It covers major code …

This paper investigates decoder diversity architectures for short low-density parity-check
(LDPC) codes, based on recurrent neural network (RNN) models of the belief-propagation …
