Novel construction of QC-LDPC codes with modified 2-D GRS codes

open access: yesTongxin xuebao, 2015
The construction method for QC-LDPC (quasi-cyclic low density parity-check) code with modified two-dimensional generalized reed-solomon (2-D GRS) code is proposed using the generator polynomial of GRS code,so thus the constructed code can have better ...

An LDPC Decoder Architecture forWireless Sensor Network Applications [PDF]

open access: yes, 2012
The pervasive use of wireless sensors in a growing spectrum of human activities reinforces the need for devices with low energy dissipation. In this work, coded communication between a couple of wireless sensor devices is considered as a method to reduce

Type-II QC-LDPC Codes From Multiplicative Subgroup of Prime Field

open access: yesIEEE Access, 2020
A quasi-cyclic (QC) low-density parity-check (LDPC) code is called type-II, if the maximum weight over all circulants appearing in the parity-check matrix has the value of two. On the basis of multiplicative subgroup analysis for the prime field, a novel

Construction Method of QC-LDPC Codes with Big Girth for Fast Encoding [PDF]

open access: yesJisuanji gongcheng, 2018
The sub-matrices on both diagonals of the right half of the check matrix are unit matrices.Existence of the deterministic unit matrix not only destroys the randomness of Quasie Cyclic-Low Density Parity Check(QC-LDPC) code,it leads to a certain loss of ...

Investigation of punctured LDPC codes and time-diversity on free-space optical links [PDF]

open access: yes, 2011
In this paper, we analyze the behavior of DVB-S2 un-punctured/punctured low-density parity-check (LDPC) coded on-off-keying (OOK) under atmospheric turbulence conditions by utilizing time diversity. A performance characterization between these schemes is
