Ampliação de Ganho de Codificação em um Código EFEC BCH para Comunicações Ópticas

Due to factors such as the growing number of internet-connected devices, the core of optical communication networks is suffering great increase in traffic. Therefore, studying alternatives that provide more capacity and robustness to these networks, including improved error correcting codes, is of fundamental importance. This paper presents data of an FPGA implementation of a BCH code derived from the channel code proposed in Annex I.9 of ITU-T Recommendation G.975.1 [1]. By increasing redundancy (parity) and by reorganizing frame structures, the new code produces a higher coding gain than the original code.
