  • Patent number: 11025364
    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.

  • Patent number: 10756882
    Abstract: A primary device implementing the subject system of link establishment for single pair Ethernet may include at least one processor. The at least one processor may be configured to transmit a first synchronization sequence to a secondary device, detect a second synchronization sequence transmitted by the secondary device, the second synchronization sequence differing from the first synchronization sequence, and after detection of the second synchronization sequence, initiate a training stage, the train stage comprising exchanging training frames with the secondary device. The at least one processor may be further configured to enter a data mode for data transmissions after completion of the training stage, the data transmissions being distinct from the training frames. In the data mode, data may be forward error correction encoded and then scrambled.

  • Patent number: 10153910
    Abstract: A transceiver, a communication system and an associated method thereof for reducing overall power consumption and complexity of the transceiver that operates over short reach twisted pair cables. The analog front end (AFE) of the transceiver communicates over at least one twisted pair that is configured only for transmission of data streams and communicates over at least one twisted pair that is only for reception of data streams. The transceiver includes circuitry that generates multiplexed and demultiplexed data streams for communication with the analog front end. Additionally, the transceiver utilizes at least certain portions of signal processing circuitry and AFE of a 10 GBASE-T transceiver or the like.

  • Patent number: 10027471
    Abstract: 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.

  • Patent number: 9577787
    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.

  • Patent number: 9553743
    Abstract: A communication device (alternatively, device) includes a processor configured to support communications with other communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other communication device(s) and to generate and process signals for such communications. For example, the device's processor receives one or more signals from a communication channel. The processor then processes the one or more signals to generate 2D DFE soft slicer outputs and to decode the one or more signals based on the 2D DFE soft slicer outputs to generate estimates of information encoded within the one or more signals. The processor may process the 2D DFE soft slicer outputs to generate 2D DFE hard decisions and then generates other estimates of the information encoded based on the 2D DFE hard decisions.
