Forward Error Correction (FEC) for High-Throughput Optical Communication
Forward Error Correction (FEC) for high-throughput optical communication has gained growing interest in the research community. The always-growing data rate (soon expected to reach 1 Tb/s) makes it necessary to look for low-complexity and low-power consumption solutions. Soft-decision (SD) decoding can guarantee top performances but it is not feasible in this setting due to its high complexity. Hard-decision (HD) decoding, especially of product codes and product-like codes, is regarded as an appealing solution due to its good performance-complexity trade-off. During the recent years, many researcher have tried to fill the performance gap between HD and SD decoding performances while keeping the complexity low.
Staircase codes are a class of product-like codes introduced in  with their HD decoding algorithm. They offer a good performance-complexity trade off, and they are adopted in recent optical standardizations (e.g. 400ZR standard). To enhance further their performances, they can be used as outer code of a concatenation scheme - with an inner SD decoded code.
The task of the student is to learn about performance-complexity trade-off in FEC for optical communications, to understand the structure and HD decoding of staircase codes and their application in the concatenated structure.
