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： Principles, apparatuses, systems, circuits, methods, and computer program products for performing a software upgrade in a MoCA network includes receiving an image of a software upgrade at a server and sending the image in the MoCA network using an L2ME message channel to a client that is enabled to receive the image and store the image in a client memory. The image may be broken up into packets, and a sequence number may be assigned to each packet to assist the client in assembling them. CRC information may also be appended to the packets to enable the client to verify their contents.

摘要： Systems and methods are provided for handling interference during communication of signals. A receive control signal may be generated in a transceiver leakage between a transmit path and a receive path in a transceiver, at least one signal applied or generated in the transmit path, and at least one signal applied or generated in the receive path. The receive control signal may then be applied adjust or control processing of received signals. One or more characteristics associated with the receive control signal may be set and/or adjusted based on one or more control signals applied to the transmit path. Transmit power may be tracked, and the receive control signal may be adjusted based on the tracking of the transmit power.

摘要： A communication system and method including the steps of receiving a first request to initiate a guaranteed quality of service flow in a network, broadcasting a second request from a Network Coordinator to a plurality of nodes connected to the network and receiving a first response to the second request from at least one ingress node. The method further includes receiving a second response to the second request from at least one egress node indicating whether the at least one egress node has available resources to receive the guaranteed quality of service flow and allocating resources for the guaranteed quality of service flow if the at least one ingress node has available resources to transmit, and the at least one egress node has available resources to receive, the guaranteed quality of service flow.

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： Systems and methods for dynamically adjusting transmit gain in a transceiver. The gain is adjusted in order to provide the maximum gain. The amount of distortion is measured. The gain is increased until the distortion reaches a predetermined limit. The gain of several components can be adjusted independently.

摘要： Methods and systems for a low-dropout regulator may comprise a voltage regulator comprising: (a) a pass transistor having a first terminal at a control gate, a voltage input at a second terminal, and a voltage output at a third terminal, and (b) an adaptive control circuit (ACC), electrically coupled to a reference voltage and each of the terminals of the pass transistor. The ACC may determine a ΔV between the second and third terminals and cause an error signal to be applied to the first terminal to keep ΔV essentially constant as the voltage input varies. The ACC may include a voltage summing circuit electrically coupled to the reference voltage and the input voltage to generate a comparison value. An error amplifier electrically coupled to the control gate and to the voltage summing circuit may generate the error signal from the comparison value and the output voltage.

摘要： Systems and methods for dynamically adjusting the gain in a receiver front end to have a desired amount of headroom, based upon a measurement of the signal to noise ratio (SNR) of the output of a digital to analog converter and the amount of degradation to the SNR due to previous adjustments to the gain.
