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: Systems and methods for canceling cross-coupled satellite signals in a LNB IC include receiving a first satellite signal at a first input of the LNB IC and filtering the first satellite signal using a first adaptive filter, the first adaptive filter having first filter coefficients; combining the adjusted first satellite signal with a second satellite signal received at a second input of the LNB IC to generate a first combined satellite signal; measuring the total output power of the combined satellite signal; changing the filter coefficients of the first adaptive filter; remeasuring the total output power of the first combined satellite signal after the changing of the first filter coefficients to determine whether the total power of the first combined satellite signal has decreased.

摘要: System and methods are provided for admission in a network comprising at least one node providing network controller (NC) functionality. A first node in the network, which is capable of generating SALTs, may assume NC functionality, and may distribute the SALT to at least one other node within the network. The first node may receive from the at least one other node, during admission to the network, a request for a dynamic encryption key, with the request being encrypted using a static encryption key unique to the at least one other node, and the static encryption key being determined based on the SALT. The first node may then send a response comprising one or more dynamic encryption keys to the at least one node, for use in network communications, wherein the response is encrypted using a static encryption key

摘要: A method, system and computer program for decompressing video data, storing the compressed video data in such a way that random access is possible and the data can be mapped efficiently into existing memory systems and interface protocols. The compression is accomplished via lossless compression using an algorithm optimized for video data. Due to the compressed format, data transmission consumes less bandwidth than using uncompressed data and prevents degradation in the decoded video.

The bit generator circuit may be operable to input into the accumulator circuit sequences meeting at least one particular criterion. The feedback circuit may be operable to apply an adjustment to a signal corresponding to an output of the accumulator circuit to generate a feedback signal, and input the feedback signal into the accumulator circuit.

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: Systems and methods for provided for reducing interference caused by leakage of signals generated by a spread spectrum phase lock loop (SS PLL). Output of SS PLL may be processed to reduce interference. For example, a sinusoidal spreading signal may be used to spread the output of the SS PLL. A notch filter tracks the frequency of the output of the SS PLL to steer the notch in the filter to the instantaneous frequency output from the SS PLL, thus allowing the notch filter to be placed in the path of signals that have unwanted leakage from the SS PLL.
