Abstract: Systems and methods are disclosed for optically communicating data by, at a transmitter side, encoding a block of input bits by one or more outer encoders, and after interleaving the encoded bits, permuting the encoded bits according to a predetermined sequence or order, and further encoding the encoded bits by an inner encoder, and at a receiver side, decoding received bits with an inner decoder, and after the encoded bits are permuted, subsequently decoding by and outer decoder, and returning information bits at an outer decoder as an output. The soft-decision and hard-decision outputs from the outer BCH code help the inner LDPC decoder to have better estimation of the received bits and gain performance. The performance in higher-order modulation formats could be as large as 0.5 dB in one embodiment.

Abstract: Embodiments of a device and method are disclosed. In an embodiment, a method for controlling CAN traffic is disclosed. The method for controlling CAN traffic involves decoding bits of an identifier of a CAN message from a TXD path, obtaining a weighted value using the decoded bits of the identifier, adding the weighted value to a running weighted value for received CAN messages, and throttling transmission of CAN messages via the TXD path if the running weighted value exceeds a pre-established threshold.

Abstract: The continuous demand for capacity and the limited available spectrum in wireless and wired communication has led to reliance on advanced modulation techniques to dramatically increase the number of bits per hertz per second. This demand in capacity and using the higher order constellations shorten the link range, and as a result, system gain becomes an important characteristic. The modulation techniques described here improve the system gain by, e.g., as much as 2.5 dB in high order modulations such as 4096-QAM. The modulation techniques include reducing the peak to average ratio and adding shaping gain. These techniques dramatically improve the system capacity, system gain, power consumption and system cost.

Abstract: Systems and methods for data transport in optical communications systems, including a transmitter for encoding a received information sequence by constructing an outer and inner quasi cyclic-low-density parity check (QC-LDPC) code. The encoding includes dividing the received information sequence into a plurality of messages of equal length, encoding each of the messages into a codeword to generate a plurality of outer codewords, cascading the plurality of outer codewords to generate a bit sequence, and executing inner encoding to encode each of the plurality of outer codewords into codewords in QC-LDPC inner code. A receiver decodes a received data stream based on the QC-LDPC inner code using two-phase decoding including iteratively performing at least one of inner/outer and outer/inner decoding until a threshold condition is reached.

Abstract: Embodiments relate to an apparatus for a regenerative network node between a first and a second link portion. The apparatus comprises an input configured to receive, from the first link portion, a signal impaired by the first link portion, the signal including a data packet with a Forward Error Correction (FEC) encoded payload portion and a header portion. The apparatus comprises a signal regeneration unit configured to mitigate signal impairments of the first link portion to provide a regenerated FEC encoded payload portion. The apparatus comprises a processing unit configured to extract destination information in the data packet's header portion. If extracted destination information indicates that the data packet's destination is the regenerative network node, the data packet's regenerated FEC encoded payload portion is forwarded to a decoding unit of the regenerative network node. Else, the data packet's regenerated FEC encoded payload portion is forwarded to the second link portion.
