Resumo
© 2019 IEEE.This paper presents the mathematical representation and the numerical results of the Gradient Bit-Flipping Algorithm (GBF) that is derived from the Bit-Flipping Algorithm (BFA).The experimental simulation results for the proposed decoder of the Low-Density Parity-Check (LDPC) codes of ATSC 3.0 demonstrate an enhancement of up to 3.55 dB in error correction performance without an increase in the decoding complexity. The proposed decoder has the ability to decode an erroneous LDPC message in fewer iterations than the traditional BFA due to the employment of the values of the Log-Likelihood Ratio (LLR) as an input, unlike the BFA that uses binary values ignoring the channel estimation output.
