High-speed ethernet coding

A BASE-T Ethernet transceiver comprising:

• a BASE-T Ethernet transmit circuit including
• a BASE-T Ethernet data framing circuitry including
• an input interface configured to receive an Ethernet block of data bits for transmission over an Ethernet interface to a receiver,
• forward error correction (FEC) encoder circuitry coupled to the input interface and configured to encode the Ethernet block of data bits to generate error correction information for use by the receiver to correct errors in a received Ethernet block of bits;
• and
• a symbol mapper configured to modulate the Ethernet block of data bits and the error correction information in accordance with a symbol constellation that includes a greater number of bit positions than a quantity of data bits in the Ethernet block of data bits.

A method of transferring Ethernet data, the method comprising:

• framing BASE-T Ethernet data including
• receiving an Ethernet block of data bits for transmission over an Ethernet interface to a receiver,
• encoding the Ethernet block of data bits in accordance with a forward error correction (FEC) code to generate error correction information for use by the receiver to correct errors in a received Ethernet block of bits;
• and
• modulating the Ethernet block of data bits and the error correction information in accordance with a symbol constellation that includes a greater number of bit positions than a quantity of data bits in the Ethernet block of data bits.
