Abstract: Methods and systems are provided for power management in communication devices, particularly based on cable connectivity. A power management component in a system may be configured to manage power use in the system based on measurements associated with a signal path used for communication by the system via a communication port, wherein the managing includes. Managing the power use may include determining, based on the measurements, connectivity related information associated with connectivity of the system via the communication port; applying, based on the connectivity related information, one or more power use reduction measures, wherein the one or more power use reduction measures include transitioning between different power related states; and monitoring one or more conditions to determine when to stop, undo, or reverse at least one of the one or more power use reduction measures.

Abstract: A method, system and computer program for transmitting at least two payloads in a downstream traffic phase of a time-division duplex (TDD) cycle with a single preamble from a headend followed by concatenated payloads without intervening preambles, whereby the payloads are ranked by increasing modulation profiles. The preamble, and concatenated and ordered set of payloads are then transmitted to two or more predetermined customer premise equipments (CPEs).

Abstract: An LDPC parity check matrix includes a systematic portion having a plurality of systematic elements and a parity portion having a plurality of parity elements. The value of each systematic element determines a cyclic shift to be applied to rows of an identity submatrix corresponding to that element. The value of each parity element determines a cyclic shift to be applied to rows of an identity submatrix corresponding to that element. The weights of two or more columns of the parity portion are the same.

Abstract: Systems and methods for admitting new nodes into an existing network, for example a MoCA network. As a non-limiting example, various aspects of the present disclosure provide systems and methods for adding a new node to an existing network without requiring on-site manual configuration, for example utilizing communication between the new node and a network coordinator of the existing network prior to admission of the new node to the existing network.

Abstract: Systems and methods are disclosed for securing a network, for admitting new nodes into an existing network, and/or for securely forming a new network. As a non-limiting example, an existing node may be triggered by a user, in response to which the existing node communicates with a network coordinator node. Thereafter, if a new node attempts to enter the network, and also for example has been triggered by a user, the network coordinator may determine, based at least in part on parameters within the new node and the network coordinator, whether the new node can enter the network.

Abstract: A wideband receiver system comprises a wideband analog-to-digital converter (ADC) module and a digital frontend (DFE) module. The wideband ADC is configured to concurrently digitize a band of frequencies comprising a plurality of desired channels and a plurality of undesired channels. The DFE module is coupled to the digital in-phase and quadrature signals. The DFE module is configured to select the plurality of desired channels from the digitized band of frequencies, and generate an intermediate frequency (IF) signal comprising the selected plurality of desired channels and having a bandwidth that is less than a bandwidth of the band of frequencies, where the generation comprises frequency shifting of the selected plurality of desired channels. The IF signal may be a digital signal and the DFE is configured to output the IF signal via a serial or parallel interface.
