Robust line coding scheme for communication under severe external noises
First Claim
1. A system comprising:
- a media independent interface circuitry configured to receive, from an automobile component, binary data and corresponding management information to be transmitted via a communication link;
an encoder circuitry configured to generate forward error correction (FEC) frames that contain the binary data and the management information; and
a communication interface circuitry configured to transmit the FEC frames that contain the binary data and the management information via the communication link.

Abstract
A system to implement a communication line coding scheme using a non-complex bit-to-symbol mapping, a forward error correction (FEC) coding, and an additive bit scrambler after the FEC at the PHY layer is provided. The system may be a part of or implemented by an automobile component. The system may be a PHY device configured to convert data from the MAC layer into 2D-PAM3 symbols that are transmitted across a communication link at a predetermined transmission rate, such as to be compliant with a communication standard. The PHY device may select characteristics of the conversion, such as the FEC coded symbol, based on the target transmission rate. The PHY device may include a transceiver, and may convert the data from MAC layer to PHY layer and back.
