Abstract
A method and apparatus for performing error correction is described. 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 and three levels of decoding.
Claims28
A method of performing 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 and three levels of decoding.

A machine-readable medium whose contents cause a computer system to perform forward error correcting, 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 and three levels of decoding.

An apparatus to perform forward error correction, comprising:
- a transceiver to receive an encoded stream of data from a transmission system, wherein said encoded stream of data was encoded using concatenated reed-solomon and turbo-code error correcting codes;
- and
- A forward error correction decoder to decode said received stream of data using said concatenated reed-solomon and turbo-code error correcting codes and three levels of decoding.
A system to perform forward error correction, comprising;
- a forward error correction encoder to encode a data stream using concatenated reed-solomon and turbo-code error correcting codes;
- a communications network to communicate said encoded data stream;
- and
- a forward error correction decoder to decode said encoded data stream using said concatenated reed-solomon and turbo-code error correcting codes and three levels of decoding.
