Abstract
A method and apparatus for performing error correction. A stream of data is encoded using concatenated error correcting codes. The encoded data is communicated over a transmission system. The encoded data is decoded using the codes.
Claims43
A method of performing error correction of transmitted information comprising:
- encoding a stream of data using concatenated reed-solomon and turbo-code error correcting codes;
- communicating said encoded data over a transmission system;
- and decoding said encoded data using said reed-solomon and said turbo-code error correcting codes.
A machine-readable medium whose contents cause a computer system to perform error correction comprising:
- encoding a stream of data using concatenated reed-solomon and turbo-code error correcting codes;
- communicating said encoded data over a transmission system;
- and
- decoding said encoded data using said reed-solomon and turbo-code error correcting codes.
An apparatus for performing error correction, comprising:
- a forward error correction encoder configured to encode a stream of data using concatenated reed-solomon and turbo-code error correcting codes;
- and
- a transceiver coupled to said encoder to communicate said encoded stream of data over a transmission system.
An apparatus for performing error correction, comprising:
- a transceiver configured to receive an encoded stream of data from a transmission system, said encoded stream of data being encoded using concatenated reed-solomon and turbo-code error correcting codes;
- and
- a forward error correction decoder configured to decode said encoded stream of data using said reed-solomon and turbo-code error correcting codes.
A system for performing error correction, comprising:
- a forward error correction encoder configured to encode a data stream using concatenated reed-solomon and turbo-code error correcting codes;
- a long-haul communication network configured to communicate said encoded stream over a distance of at least 600 kilometers;
- and
- a forward error correction decoder configured to decode said encoded data stream using said concatenated reed-solomon and turbo-code error correcting codes.
