Abstract: A microwave backhaul transceiver comprises a plurality of antenna arrays, positioning circuitry, and signal processing circuitry. The microwave backhaul transceiver may determine, via the positioning circuitry, a location of the small cell backhaul transceiver. The microwave backhaul transceiver may, generate, via the signal processing circuitry, a beacon signal that uniquely indicates the location. The microwave backhaul transceiver may transmit the beacon signal via at least one of the antenna arrays. The beacon signal may be generated using a spreading code generated from a unique identifier of the location. The unique identifier of the location may comprise global positioning system coordinates and/or a street address. During the transmitting, a directionality at which the beacon radiates from a particular one of the antenna arrays may be varied such that the beacon is transmitted in multiple directions from the particular one of the antenna arrays.

Abstract: A system comprises local oscillator spur suppression circuitry, local oscillator generator circuitry), and beamforming circuitry. The local oscillator spur suppression circuitry is operable to generate a phase adjustment value. The local oscillator generator circuitry is operable to generate a local oscillator signal at a determined phase equal to a reference phase offset by the phase adjustment value. The beamforming circuitry is operable to receive the phase adjustment value, and generate a beamforming coefficient to be applied to a signal that is to be upconverted by the local oscillator signal and transmitted via an antenna element of a phased array, wherein the generation of the beamforming coefficient is based on the phase adjustment value and a location of the antenna element within the phased array.

Abstract: Methods and systems are provided for power control in communications devices. Bonding of channels in communication devices may be dynamically adjusted, such as responsive to requests for bandwidth adjustment. For example, bonded channel configurations may be adjusted based on power, such as to single channel configurations (or to channel configurations with small number of channels, such as relative to current configurations) for low power operations. Components (or functions thereof) used in conjunction with receiving and/or processing bonded channels may be dynamically adjusted. Such dynamic adjustments may be performed, for example, such as to maintain required synchronization and system information to facilitate rapid data transfer resumption upon demand.

Abstract: A system comprises a plurality of antenna elements, a transmitter circuit, and first and second receiver circuits. The transmitter is operable to: transmit, via a first antenna element, a series of signals having a calibration component and each of the signals being generated with a different configuration of the transmitter circuit; and select a configuration for a future transmission based on a signal metric. The first receiver circuit is operable to: receive the signal via a second antenna element; and detect the calibration component in the signal to generate a first calibration signal. The second receiver circuit is operable to: receive the signal via a third antenna element; detect the calibration component in the signal to generate a second calibration signal; combine the first and second calibration signals to generate a combined calibration signal; and generate the signal metric based on the combined calibration signal.

Abstract: A radar transmitter comprises orthogonal frequency division multiplexing (OFDM) symbol generation circuitry, windowing circuitry, and control circuitry. The OFDM symbol generation circuitry is operable to modulate data onto a plurality of subcarriers to generate a plurality of OFDM symbols. The windowing circuitry is configurable to support a plurality of windowing functions. The control circuitry is operable to analyze returns from a previous transmission of the radar transmitter to determine characteristics of the environment into which the previous transmission was transmitted. The control circuitry is operable to select which one of the plurality of windowing functions the windowing circuitry is to apply to each of the plurality of OFDM symbols based on the characteristics of the environment. A first one of the windowing functions may correspond to a first radiation pattern and the second one of the windowing functions may correspond to a second radiation pattern.

Abstract: An array based communications system may comprise a plurality of element processors. Each element processor may comprise a combining circuit, a crest factor circuit, and a phase shifter circuit. The combining circuit may produce a weighted sum of a plurality of digital datastreams. The crest factor circuit may be operable to determine whether the weighted sum has a power above or below a power threshold. If the power is above the power threshold, the crest factor circuit is operable to reduce the power. If the power is below the power threshold, the crest factor circuit is operable to increase the power. The phase shifter circuit may introduce a phase shift to out-of-band components of the weighted sum according to the power increase or the power decrease by the crest factor circuit.

Abstract: Methods and systems for cross-protocol time synchronization may comprise, for example, in a premises-based network, receiving a signal that conforms to a data over cable service interface specification (DOCSIS) communications protocol. A global time of day (GTOD) clock may be extracted from the received signal. Communication on the premises-based network in accordance with a multimedia over cable alliance (MoCA) communications protocol may be synchronized based at least in part on the extracted GTOD clock. Communication in a third communications protocol may be synchronized, wherein the third communications protocol may include a home phoneline networking alliance (HPNA) standard, an IEEE 802.11x standard, and a non-public wireless network protocol. The extracted GTOD clock may comprise a GPS clock, GLONASS clock, and a Galileo clock. A second signal for extracting a GTOD may be received, such as a satellite signal, and may conform to a low Earth orbit satellite signal protocol.
