摘要： 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.

摘要： A vehicle communication network device includes a transceiver configured to communicatively couple with a remote transceiver of another vehicle communication network device via a wired media and processing circuitry coupled to the transceiver. The device detects interference on the wired media that exceeds an interference threshold level. Upon the detection, the device enters a quiet mode during which no data is transmitted on the wired media. After exiting the quiet mode, the device enters an idle mode during which known data is transmitted on the wired media and during which the device receives known data from the remote transceiver. The device retrains its transceiver based upon the known data and after retraining the transceiver, exchanges data with the remote transceiver. The device may also buffer data for transmission, upon the detection, determine buffered data that was likely corrupted by the interference, and after retraining, retransmit the determined buffered data.

摘要： 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.

摘要： A device for common mode (CM) clamping in wired communication includes a first circuit and a second circuit. The first circuit is configured to sense a voltage signal across clamp terminals and to generate an output voltage signal based on the sensed voltage signal. The second circuit is configured to compare the output voltage signal with a reference voltage, to generate a pair of current signals based on a result of the comparison, and to provide the pair of current signals to the clamp terminals. The pair of current signals includes a matched pair of CM current signals. The clamp terminals, upon coupling to nodes of a main circuit provide a desired CM impedance between the nodes of the main circuit. The device can be coupled to the main circuit in conjunction with one or more off-chip magnetic components.

摘要： A primary device implementing the subject system of link establishment for single pair Ethernet may include at least one processor circuit. The at least one processor circuit may be configured to transmit a first synchronization sequence to a secondary device and to subsequently detect a second synchronization sequence, different than the first, transmitted by the secondary device. The synchronization sequences may be pseudo-noise sequences that have strong autocorrelation characteristics. The at least one processor circuit may be configured to wait a predetermined amount of time after completing the detection of the second synchronization sequence, and then may initiate a training stage. The training stage may include exchanging scrambler states of additive scramblers used by the primary and secondary devices. The at least one processor circuit may be configured to enter a data mode upon completion of training. In the data mode, data is forward error correction encoded and then scrambled.

摘要： In the subject system for remote monitoring and configuration, management of a remote physical layer device may be performed by receiving, at a local physical layer device, an incoming message of a first communication format from a controller device. The incoming message may include a request intended for the remote physical layer device that is communicatively coupled to the local physical layer device over a transmission line carrying a data channel and a supplemental channel. The incoming message may be parsed into an outgoing message of a second communication format for sending to the remote physical layer device through the supplemental channel. The local physical layer device may receive a response from the remote physical layer device through the supplemental channel. The local physical layer device may convert the response from the second communication format into the first communication format for sending the converted response back to the controller device.
