  • Patent number: 10860938
    Abstract: After sensors are placed at three or more non-collinear locations on a surface of the component, the system receives time-series signals from the sensors while the component operates on a representative workload. The system then defines one or more triangles on the surface of the component, wherein each triangle is defined by three vertices, which coincide with different sensor locations on the surface of the component. For each triangle, the system applies a barycentric coordinate technique (BCT) to time-series signals received from sensors located at the vertices of the triangle to determine a candidate location within the triangle to place an additional sensor. The system then compares the candidate locations for each of the one or more triangles to determine a globally optimal location for the additional sensor, and a new sensor is placed at this location. This process is repeated until a desired number of sensors are placed.

    Abstract: A digitally-controlled power amplifier (DPA) includes a radio frequency digital-to-analog converter (RF-DAC) constructed from nonlinearly weighted PA segments, a multiphase RF drive signal generator that drives the PA segments, and overdrive voltage control circuitry. The nonlinear weighting of the PA segments intrinsically compensates for amplitude-code-word dependent amplitude distortion (ACW-AM distortion) involved in the operation of the RF-DAC and the multiphase RF drive signal generator facilitates ACW-dependent phase distortion (ACW-PM distortion) reduction, thus obviating the need for complicated and efficiency-degrading digital predistortion. The overdrive voltage control circuitry is used to fine tune the RF output of the DPA and compensate for other non-idealities and external influences such as process, voltage, temperature (PVT), frequency and/or load impedance variations.

  • Patent number: 10638517
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may use a subband of a frequency domain channel as a dedicated channel reservation (CR) sub-channel. Wireless devices may both monitor for and transmit CR signals in the CR subband. When not actively transmitting, a wireless device may monitor the CR subband to identify CR signals from other wireless devices. A wireless device communicating using the CR subband may transmit a CR signal and a pre-grant or pre-grant response simultaneously based on an frequency division multiplexing configuration. Multiple channels may share a CR subband. The CR subband may have a pre-configured frequency domain location or be at a configurable frequency in the channel. The data subband and CR subband may have different levels of synchronization, and base stations operating in the wireless communications system may consider data subband synchronization and CR subband synchronization separately.

  • Patent number: 10624067
    Abstract: A method for adaptively allocating resources of an uplink control channel according to a system situation is disclosed. If a base station (BS) recognizes the system situation, establishes control information for resource allocation, and transmits the control information to a mobile station (MS), the mobile station (MS) allocates resources for transmitting uplink control information using a specific block or a specific resource distribution method according to the corresponding control information. The system situation may be changed according to the number of users contained in the BS's coverage or the usage of a multi-antenna. The variation of the system situation is actively reflected so that the uplink channel resources can be effectively used.

  • Patent number: 10613777
    Abstract: Aspects of the disclosure relate to ensuring information security in data transfers by utilizing decoy data. A computing platform may receive, from a data source computing device, a source data collection for a secure physical-storage-media data transfer and may identify one or more transmission parameters associated with the secure physical-storage-media data transfer. Subsequently, the computing platform may generate decoy data and may produce a secure dataset for the secure physical-storage-media data transfer by combining the decoy data with the source data collection received from the data source computing device. Then, the computing platform may encrypt the secure dataset based on the one or more transmission parameters to produce an encrypted dataset for the secure physical-storage-media data transfer.

  • Patent number: 10581494
    Abstract: A base station, e.g., for massive MIMO, has channel receivers, each connected to a respective antenna among a plurality of antennas to receive an RF transmission signal generated by a communication device (CD). Each channel receiver has a channel front-end module, which has a first bandwidth and converts the RF transmission signal into one or more first analog baseband signals. The channel receivers are collectively operable to define a spatial beam focus at the CD, based on channel state information of the CD. The base station has pilot signal receivers, each connected to a respective antenna among the plurality of antennas to receive an RF pilot signal generated by the CD or another CD. Each pilot signal receiver has a pilot signal front-end module, which has a second bandwidth that is smaller than the first bandwidth and converts the RF pilot signal into one or more second analog baseband signals.

  • Patent number: 10566955
    Abstract: An improved sliding discrete Fourier transform (SDFT) algorithm called CIC-SDFT and its apparatus are provided. An input signal is multiplied by a modulated twiddle factor, and is then processed by a modified cascade integrator-comb (CIC) filter. The CIC-SDFT comprises an integrator section and a comb section, with a downsampler disposed between the two sections to enable downsampling of the SDFT computations. Through addition of more integrator stages and comb stages to the CIC-SDFT, the accuracy of spectrum estimation may be improved in a computationally inexpensive manner and with less complexity than applying windowing functions to known SDFTs. Various embodiments provide a partially-nonrecursive method of CIC-SDFT that further decreases computational complexity.

  • Patent number: 10530418
    Abstract: An apparatus includes an input node, an output node, and successive butterfly elements connected between the input node and the output node. Each butterfly element includes a first branch and a second branch that are cross-coupled with each other and that perform, collectively, sample add and sample delay operations. Either the first branch or the second branch of each butterfly element performs a sample inversion, such that a pattern of the sample inversions across the butterfly elements encodes into the butterfly elements a pattern of negative and positive binary values of a particular row of a Prometheus Orthonormal Sets (PONS) matrix. As a result, the successive butterfly elements correlate input samples applied to the input node against the particular row of the PONS matrix as the input samples are shifted through the successive butterfly elements.
