Abstract

We propose a rate-adaptive forward error correction (FEC) scheme based on spatially-coupled (SC) LDPC codes derived from quasi-cyclic (QC) LDPC codes with its field-programmable gate array (FPGA) architecture. By FPGA emulation, we show that, with comparable computational complexity, the proposed LDPC codes provide larger coding gain and smaller error floor compare to the QC-LDPC base code. As a result, due to its hardware friendly structure, they are presented to be a promising candidate for the next-generation intelligent optical communication systems such as long-haul optical transmission system.
