摘要： 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.

摘要： 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.

摘要： A method for managing data transmission comprising making a bandwidth on a network resource available to at least one requestor for transmitting or receiving data according to a first request of a first type, the first type have a prescribed quality of service guarantee; transmitting first data in accordance with the first type to or from the at least one requestor on the network resource using a first portion of the bandwidth, if the first data are available to be transferred to or from the at least one requestor; transmitting second data according to a second request of a second type on the network resource to or from the at least one requestor or a second requestor, the second data transmitted without a quality of service guarantee using a second portion of the bandwidth, if the first portion of the prescribed bandwidth is less than the entire bandwidth.

摘要： A USB-to-coaxial network bridging system and method includes receiving data frames from a USB or FireWire device via a corresponding USB or FireWire communication interface, wherein the received data frames are intended for transmittal to a predetermined remote device on a coaxial network; combining the received data frames into an aggregated frame and addressing the aggregated frame to allow the aggregated frame to be routed to the predetermined remote device on the coaxial network; and sending the aggregated frame to the remote device over the coaxial network.

摘要： An outdoor satellite receiving unit (ODU) receives several independent satellite signals, selects two signals with a switch matrix, downconverts the two signals to a bandstacked signal with a high and a low band signal, and outputs the bandstacked signal on the same cable to receiver units. Several satellite signals can be selected in groups of two or more and output to independent receiver units. Signal selecting is performed at the received radio frequency (RF) and bandstacking is performed with a single downconversion step to an intermediate frequency (IF). Channel stacking on the same cable of more than two channels from several satellites can be achieved by using frequency agile downconverters and bandpass filters prior to combining at the IF output. A slow transitioning switch minimizes signal disturbances when switching and maintains input impedance at a constant value.

摘要： A particular overall architecture for transmission over a bonded channel system consisting of two interconnected MoCA (Multimedia over Coax Alliance) 2.0 SoCs (Systems on a Chip) and a method and apparatus for the case of a “bonded” channel network. With a bonded channel network, the data is divided into two segments, the first of which is transported over a primary channel and the second of which is transported over a secondary channel.

摘要： 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).
