Abstract
A system and method for coding technique which achieves a high coding gain with simple, low-price implementation. The system comprises a transmitter for transmitting encoded code words, and a receiver for receiving and decoding the code words, via a network. In one embodiment, a low complexity modified R-S coding process is used to R-S encode smaller-bit words (e.g., 7-bit words, instead of 8-bit words). In a second embodiment, a feed-back block concatenated coding process improves coding gain by utilizing concatenation and an erasure algorithm. In a third embodiment, a feed-back block concatenated coding process is designed for an Ethernet. The decoding processes utilize error-correcting capabilities built in during the three encoding processes described herein.
