Abstract
The present invention provides a system (100), device (400, 500) and method (600, 700) for forward error correction (FEC) coding and interleaving in a variable length burst transmission communications system. The system incorporates at least one shortened FEC encoder to accomplish FEC coding and burst interleaving for transmission from a variable length burst data source. Decoding/de-interleaving is accomplished by a device consisting of at least one fixed length FEC decoder. The technique of padding with zero symbols at the end of burst is used in the device to allow decoding with fixed length FEC decoders and for minimizing delay.
