Abstract:
A communication technique for energy efficient Ethernet (EEE) employs a systematic block forward error correcting code (FEC). The technique aligns a low power idle (LPI) refresh signal with the FEC frame. The refresh signal includes a known reference sequence, FEC systematic symbols, and FEC parity symbols. The technique may apply shortened FEC encoding and decoding on the partial data symbols and the parity symbols.
