The FEC code used is a shortened cyclic code (2112, 2080) for error checking and forward error correction. The code encodes 2080 bits of payload (or information symbols) and adds 32 bits of overhead ...

Traditionally, it has been assumed that for a given FEC code, a required post-FEC BER can be translated into an equivalent required pre-FEC BER. Called the FEC limit paradigm, this approach allowed ...

Consequently, a variety of “second generation” codes with the same 6.7% overhead as the G.709 standard FEC were developed, including turbo product codes and low-density parity check (LDPC).

An enhanced forward error correction (FEC) code is said to improve the speed of data communications and multimedia applications. In addition, these Vector-Low-Density ...

3.5.2 Media-Dependent FEC As we mentioned, it is desirable that the FEC technique introduces as little extra delay as possible. Ideally, we would like FEC codes that spread only a single block.
