The concatenated code is theoretically analyzed. The theoretical analyses and simulation results show that inner-outer concatenated code has a greater redundancy and the decoding of parallel concatenated code is too complex. However, consecutive concatenated code is superior coding scheme with http://link.springer.com/article/10.1007/s12200-008-0056-7 advantages such as better error correction performance, moderate redundancy and easy implementation, therefore it could be better used in high-speed and long-haul DWDM systems.Keywordsdense wavelength-division multiplexing (DWDM) systemsuper forward error correction (Super-FEC)concatenated codenet coding gain (NCG)__________Translated from Laser Journal, 2007, 28(2): 67–69 [译自: 激光杂志]References1.ITU-T G. 975.

Aug 21, 2000 Contributing Author | Electronic Design forward error correction EMAIL Tweet Comments 0 As bandwidth demands increase and the tolerance for errors and latency decreases, designers of data-communication systems are looking for new ways to expand available bandwidth and improve the quality of transmission. One solution isn't actually new, but has been around for a while. Nevertheless, it could prove quite useful. Called forward error correction (FEC), this design technology has been used for years to enable efficient, high-quality data communication over noisy channels, such as those found in satellite and digital cellular-communications applications. Recently, there have been significant advances in FEC technology that allow today's systems to approach the Shannon limit. Theoretically, this is the maximum level of information content for any given channel. These advances are being used successfully to reduce cost and increase performance in a variety of wireless communications systems including satellites, wireless LANs, and fiber communications. In addition, high-speed silicon ASICs for FEC applications have been developed, promising to further revolutionize communication systems design. The big attraction of FEC technology is how it adds redundant information to a data stream. This enables a receiver to identify and correct errors without th
