On the Gap to Channel Capacity of Generalized Low-Density Parity-Check Codes

open access: yesIEEE Open Journal of the Communications Society
In this study, the gap to channel capacity of generalized low-density parity-check (GLDPC) codes under the a posteriori probability (APP) decoder on the binary input additive white Gaussian noise (BI-AWGN) channel is analyzed.

Fbmc System With Low Density Parity Check (Ldpc) Coding For Efficient Communications In 5g

open access: yesInternational Journal of Engineering and Advanced Technology, 2019
Channel coding is a complicated subject, but vital in cellular communications, which is used for detection and correction of the bit errors caused by various types of noises, interferences. In 3rd generation and 4th Generation (3G and 4G) cellular communications, Turbo codes are predominantly used and currently 3GPP standardization group considering ...

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 ...

FPGA Implementation of encoders for CCSDS Low-Density Parity-Check (LDPC) codes.

open access: yes, 2015
The FPGA implementation of LDPC encoders for channel codes standardized by CCSDS for space communication applications is described in this work. CCSDS suggests two classes of channel codes for telemetry applications: one for near-earth and another for deep-space communications, each one optimized for the demands of the specific field.
