A power amplifier with supply switching is provided. The power amplifier detects a magnitude of an outgoing broadband communication signal and determines whether the magnitude exceeds a predetermined voltage threshold. The power amplifier applies a first gain to the outgoing broadband communication signal using a first voltage supply rail when it is determined that the magnitude exceeds the predetermined voltage threshold and a second gain using a second voltage supply rail that is smaller than the first voltage supply rail when it is determined that the magnitude does not exceed the predetermined voltage threshold. The power amplifier produces an output signal from the outgoing broadband communication signal with the applied first gain or the applied second gain, wherein a current of the outgoing broadband communication signal is switched between the first voltage supply rail and the second voltage supply rail in response to the magnitude being detected.

Power amplifier with supply switching

A device includes circuitry configured to implement one or more PHY communications protocols to simultaneously communicate with one or more stations via communication links on one or more wireless networks, communicate with additional devices via a backhaul network, and exchange collaboration data, including at least one of protocol data or collaborative beamforming data, with the additional devices via the backhaul network to maintain signal parameters of communications signals with the one or more stations.

Collaborative operation of software defined radios

Method and apparatuses are disclosed to substantially compensate for various unwanted interferences and/or distortions within a communications receiver. Each of these apparatuses and methods estimate the various unwanted interferences and/or distortions within the communications receiver. Each of these apparatuses and methods remove the estimates of the various unwanted interferences and/or distortions within the communications receiver from one or more communications signals within the communications receiver to substantially compensate for the various unwanted interferences and/or distortions.

Compensating for unwanted interference in a communications receiver

Provided is a packet network adapter operable to receive a satellite intermediate frequency (IF) signal and determine whether the satellite IF signal includes DVB content based upon a network client request. When the satellite IF signal includes the requested DVB content, the satellite network adapter produces packetized data for delivery of the digital content to a network client or clients based upon the network client request.

Internet protocol low noise block front end architecture

A transmitter for use in a cable modem termination system includes a data processing module that generates a plurality of OFDM symbols from a data packet. A probe symbol generator generates a probe symbol, as one of a plurality of probe symbol types. The probe symbol is selectively inserted within the plurality of OFDM symbols, at a pre-defined probe symbol interval.

Communication system with proactive network maintenance and methods for use therewith

A device includes circuitry configured to detect one or more properties of an image signal based on outputs from one or more (analog-to-digital converter) ADC configurations of a transceiver, determine a VCO frequency corresponding to an ADC sampling frequency independently from a carrier frequency, and control the VCO frequency of at least one of a transmitter or receiver based on the one or more properties of the image signal.

System, device, and method for improving radio performance

A method and apparatus is disclosed to restrict the delivery of video, audio, and/or data to unauthorized end users in a satellite communications system. The satellite communications system includes one or more satellite receiving antennas, commonly referred to as a satellite dish, to receive downlink communications signals from one or more satellites. The transmission received by the one or more satellite receiving antennas is converted by an outdoor unit (ODU) for transmission to one or more indoor units (IDUs). The ODU receives control information from one or more satellites from the downlink communications signals, commonly referred to as in-band, and/or from out-of-band communications signals. The ODU may use the control information to restrict access to one or more communications channels embedded within the downlink communications signals to the unauthorized end users.

Conditional access system for satellite outdoor unit

A device includes circuitry configured to determine noise shaping parameters for one or more transmit signals on one or more transmit channels based on transmission protocol and spectral mask criteria. Frequency positions are identified for the one or more transmit channels based on the noise shaping parameters, and the noise shaping parameters are applied to the one or more transmit signals.

System, device, and method for shaping transmit noise

A system, method, and apparatus to allow an operator of a broadcast communication system, such as a cable television or satellite television service to provide some examples, to diagnose performance of this communication system remotely. The operator of a first communication device, such as a cable modem termination system (CMTS) to provide an example, may remotely diagnosis performance problems, or potential performance problems, occurring at a second communication device, such as a cable modem (CM) to provide an example, or a group of second communication devices. For example, the operator of the first communication device may view a spectrum analysis of communication signals being routed to, processed by, and/or provided by the second communication device, or group of second communication devices, to diagnose the performance problems, or the potential performance problems, in real time.

Spectrum analysis and plant diagnostic tool for communications systems

A device includes circuitry configured to assess a broadband spectrum environment including signal and blocker characteristics via one or more receiver paths, determine operational parameters for the device based on the signal and blocker characteristics, and align one or more radio components from one or more radios for operation based on the operational parameters of the device.

System, device, and method for combining software defined radios

A method and apparatus is disclosed to couple a transmission amplifier and a reception amplifier to a shared medium. An output of the transmission amplifier is directly coupled to an input of the reception amplifier to form a common connection. The transmission amplifier and the reception amplifier may receive a first amplifier bias via the common connection. In response to the first amplifier bias, the transmission amplifier provides a first communication signal to the shared medium and the reception amplifier does not provide a second communication signal from the shared medium. Alternatively, the transmission amplifier and the reception may receive a second amplifier bias via the common connection. In response to the second amplifier bias, the reception amplifier provides the second communication signal from the shared medium and the transmission amplifier does not provide the first communication signal to the shared medium.

Direct coupled radio frequency (RF) transceiver front end

A communication device (e.g., a cable modem (CM)) includes a digital to analog converter (DAC) and a power amplifier (PA) that generate a signal to be transmitting via a communication interface to another communication device (e.g., cable modem termination system (CMTS)). The CM includes diagnostic analyzer that samples the signal based on a fullband sample capture corresponding to a full bandwidth and/or a subset (e.g., narrowband) sample capture to generate a fullband and/or subset signal capture (e.g., of an upstream (US) communication channel between the CM and the CMTS). The diagnostic analyzer can be configured to generate sample captures of the signal based on any desired parameter(s), condition(s), and/or trigger(s). The CM then transmits the signal to the CMTS and the fullband and/or subset signal capture to the CMTS and/or a proactive network maintenance (PNM) communication device to determine at least one characteristic associated with performance of the US communication channel.

Noise localization within cable based communication systems

The present invention is an integrated cable modem tuner. In one embodiment, the upstream path and the downstream path are integrated on a common semiconductor substrate. The down-stream path can include a TV tuner and digital receiver portion that is integrated on a common semiconductor substrate with the power amplifier of the upstream path. In another embodiment, the TV tuner is implemented on a first semiconductor substrate and the digital receiver portion and the power amplifier are configured on a second semiconductor substrate. However, the two substrates are mounted on a common carrier so that the cable modem appears to be a single chip configuration to the user.
