Abstract

An error correction method is disclosed, including receiving an input data, processing the input data with a first Forward Error Code (FEC) transformation, processing the input data with a second FEC transformation, and generating an output data including the first transformation and the second transformation.

Claims

1. An error correction method, comprising:

receiving an input data;

processing the input data with a first Forward Error Code (FEC) transformation;

processing the input data with a second FEC transformation; and

generating an output data including the first transformation and the second transformation.

2. The method according to claim 1, wherein the first and second FEC transformations comprise FEC encoding or FEC decoding transformations.

3. The method according to claim 1, wherein the first FEC transformation comprises a regular FEC (rFEC) transformation.

4. The method according to claim 1, wherein the second FEC transformation comprises an enhanced FEC (eFEC) transformation.

5. The method according to claim 1, with the first FEC transformation and the second FEC transformation comprising a concatenated processing.

6. The method according to claim 1, with the first FEC transformation and the second FEC transformation comprising a concatenated processing and with each data block being transformed by both the first FEC transformation and the second FEC transformation.

7. The method according to claim 1, with the first FEC transformation and the second FEC transformation comprising a parallel processing.

8. The method according to claim 1, with the first FEC transformation and the second FEC transformation comprising a parallel processing and with first data blocks transformed by the first FEC transformation being interleaved with second data blocks transformed by the second FEC transformation.

9. The method according to claim 1, wherein the first FEC transformation and the second FEC transformation are based on a link condition.

10. The method according to claim 1, further comprising processing the input data with at least a third FEC transformation.

11. A network device, comprising:

a transceiver configured to receive an input data; and

a processor coupled to the transceiver and configured to;

process the input data with a first Forward Error Code (FEC) transformation;

process the input data with a second FEC transformation; and

generate an output data including the first transformation and the second transformation.

12. The network device according to claim 11, wherein the first and second FEC transformations comprise FEC encoding or FEC decoding transformations.

13. The network device according to claim 11, wherein the first FEC transformation comprises a regular FEC (rFEC) transformation.
