Abstract: A receiver circuit is disclosed and is configured to receive an optical signal. The receiver circuit includes a receiving circuit configured to receive the optical signal and convert the optical signal from a duobinary signal format into a binary signal based on a plurality of decision thresholds. The receiver circuit also includes a clock data recovery circuit configured to sample the binary signal per data period at a first time instant based on a predetermined clock data recovery technique, and sample the binary signal per data period at a second time instant offset from the first instant, as well as determine an intermediate sample based on an offset for decoding a transmitted bit sequence according to soft information based on the samples.

Abstract: A node circuit associated with a hybrid fiber coax (HFC) network is disclosed. The node circuit includes an optimizer circuit configured to process a plurality of signal-to-noise ratio (SNR) values associated with a plurality of subcarriers, respectively, associated with a set of cable modem (CM) circuits coupled to the node circuit. In some embodiments, the plurality of subcarriers comprises subcarriers that are allocated to the set of CM circuits for communication with the node circuit. In some embodiments, the optimizer circuit is further configured to determine an optimal transmit power of the node circuit, based on the plurality of SNR values and a distortion model of a transmitter circuit associated with the node circuit. In some embodiments, the distortion model defines a transmitter distortion associated with the transmitter circuit.

Abstract: An on-chip data packet processing method and corresponding integrated circuit, wherein data packets are received at an ingress port and processed with an on-chip wire-speed engine. The processing comprises adding metadata to the data packets, forwarding the processed data to an on-chip QoS unit, altering the metadata of the data packets and/or providing further metadata to the data packets. The data packets are forwarded from the on-chip QoS unit to an on-chip data consumer. If the data consumer is a processing unit the data packets are processed in a first processing step, redirected from the processing unit to the QoS unit and the step of forwarding the data packets to an on-chip data consumer is repeated.

Abstract: A receiver may include a first filter configured to generate a first estimation of a symbol of a received signal and a second filter configured to generate a second estimation of the symbol of the received signal. The receiver may also include a decoder configured to decode the symbol using one of the first estimation and the second estimation and a decision circuitconfigured to select one of the first estimation and the second estimation to provide to the decoder for decoding of the symbol based on a comparison of the first estimation to an estimation threshold.

Abstract: An electronic communication device comprises echo cancellation circuitry and signal modification circuitry. The echo cancellation circuitry may be operable to generate a first signal that approximates interference present in a second signal. The signal modification circuitry may be operable to generate a first cancellation signal in a frequency band that is not used on a communication medium over which the electronic communication device is configured to communicate. The signal modification circuitry may be operable to combine the first cancellation signal with the first signal, wherein the combining of the signals results in a modified first signal that has a lower crest factor and/or peak-to-average power ratio than the first signal. The signal modification circuitry may be operable to combine the modified first signal with the second signal to reduce interference present in the second signal.

Abstract: A hardware system for signature matching in a distributed network is disclosed. The hardware system comprises a network processor and a memory. The network processor is configured to perform horizontal compression on a state table using bitmaps, wherein the state table has a plurality of states and state transitions. The processor is also configured to perform a first grouping of states of the state table using the bitmaps to generate a first one or more sets of states, perform a second grouping of states of the state table based on the first one or more sets of states and a transition threshold to generate a second one or more sets of states, perform a conquer step grouping of the states of the state table based on the second one or more sets of states and conquer criteria to generate third one or more sets of states, and generate a two dimensioned compressed state table based on the third one or more sets of states. The memory circuit is configured to store the two dimensioned compressed state table.

Abstract: Methods and systems are provided for power control in communications devices. Bonding of channels in communication devices may be dynamically adjusted, such as responsive to requests for bandwidth adjustment. For example, bonded channel configurations may be adjusted based on power, such as to single channel configurations (or to channel configurations with small number of channels, such as relative to current configurations) for low power operations. Components (or functions thereof) used in conjunction with receiving and/or processing bonded channels may be dynamically adjusted. Such dynamic adjustments may be performed, for example, such as to maintain required synchronization and system information to facilitate rapid data transfer resumption upon demand.
