Abstract

See full text

A local area network (LAN) backbone is implemented within an environment such as a self-contained environment (e.g., an automobile, an aircraft, a train, a ship, and/or any other environment). The LAN backbone is affected by AWGN, NBI, and/or impulse noise (noise). The LAN backbone supports communications based on an Ethernet communication protocol (e.g., a 1000Base-T1 based system that includes at least one single twisted pair). A device receives a first LDPC coded signal via the LAN backbone and decodes it to recover an input signal of a control system. The device also uses soft information generated during the decoding to compensate for the noise affecting the LAN backbone and then processes the input signal to generate a control signal for the control system. The device then and encodes the control signal to generate a second LDPC coded signal and transmits the second LDPC coded signal via the LAN backbone.
