  • Publication number: 20150103815
    Abstract: The present invention provides a method and system for reducing the peak to average power ratio (PAP) of a signal with low computational complexity. According to one embodiment, the present invention is applied to reduce the PAP of an OFDM signal. According to an alternative embodiment, the present invention, is applied to reduce the PAP of a CDMA signal. Rather than seeking the optimum solution, which involves significant computational complexity, the present invention provides for a number of sub-optimal techniques for reducing the PAP of an OFDM signal but with much lower computational complexity.

  • Publication number: 20150073894
    Abstract: Events and metrics from time series data are analyzed to detect unexpected spikes and dips or other unpredictable occurrences. In time series measurement of a metric it is not uncommon for a particular metric to have predictable deviations from a median value. For example, activity on a particular “weekday” web site may be more intense during weekdays and have very little activity on weekends. A different web site might have the opposite “normal” activity profile. If the “weekday” web site were to have a large amount of activity on a Saturday and/or Sunday then that large amount of activity may be considered unpredictable and be classified as a “suspect anomaly.” Techniques to identify and novel presentation of suspect anomalies are presented in this disclosure.

  • Patent number: 8933971
    Abstract: A device may display a presentation of elements (e.g., icons) on a display component. However, display components have a pixel density that affects aesthetic and practical aspects of the presentation (e.g., rendering the presentation at a variable and inconsistent size); yet, many presentations are not generated in view of the pixel density of the display component of the device. Presented herein are techniques for generating and displaying a presentation of elements in view of the pixel density of the display component, using a scale factor set of scale factors that specify a pixel density range and a scale factor value (e.g., 120%) to be applied to the elements of the presentation. The scale factor set may be kept small to reduce the administrative burden on the designer of the element, while also achieving approximately consistent sizing of the presentation on display components having variable pixel densities.

  • Patent number: 8933952
    Abstract: This document describes techniques for pre-rendering new content for an application-selectable user interface. These techniques permit a user to select to view application-selectable tiles of the interface and, on selection, quickly see new content through the tiles in the selected portion. In some embodiments, the techniques pre-render content for a portion of a non-visible region of the interface rather than all of the non-visible region to reduce resource costs, such as processor and memory usage on a device and communication bandwidth usage on a communication network.

  • Publication number: 20140314187
    Abstract: An OFDM system embeds sequence information in the transmitted signal that reduces peak average power ratio (PAP) with minimal impact on the overall system efficiency. A marker is embedded onto the transmitted information that is used to identify the combining (inversion) sequence at the receiver. In one embodiment, selected tones in a cluster are rotated when the corresponding phase factor rotates the cluster.

  • Publication number: 20140301497
    Abstract: A rate-adaptive method of communicating over a multipath wireless communication system uses multiple links such that each end of a link uses multiple transmit and receive antennas. A number of independent streams that are to be transmitted for each link is determined based on an overall system performance measure. In addition, the system may also jointly determine the best modulation, coding, power control, and frequency assignment for each link, based on an overall system performance measure. In OFDM systems, the number of independent streams, as well as the modulation, coding, and power control, may be determined on a tone-by-tone basis based on an overall system performance measure.

  • Publication number: 20140293806
    Abstract: Certain aspects of a method and system for a fast cell search using a primary synchronization channel (PSYNC) process in a multimode wideband code division multiple access (WCDMA) terminal are provided. A WCDMA frequency search or a global system for mobile communications (GSM) frequency search is performed based on a current radio access technology (RAT), received signal strength indication (RSSI) scan measurements, and PSYNC detection operations. The RSSI scan measurements may be averaged by making multiple measurements during a measurement period. At least part of the PSYNC detection operations may be performed during a remaining portion of the measurement period. WCDMA carrier frequencies may be marked in accordance with the results of the PSYNC detection operations. For GSM, some of the frequencies may be removed from the search based on the PSYNC marking while the remaining search frequencies may be ranked based on results from the RSSI scan measurements.

  • Patent number: 8830270
    Abstract: This document describes techniques for progressively indicating new content in an application-selectable user interface. These techniques permit a user to view indications of new content for applications progressively, rather than all at one time. By so doing, the techniques may avoid mentally or visually overloading or over-stimulating a user viewing the indications.

    Abstract: A wireless multiple-input multiple output (MIMO) communication system includes signaling simulcasting. Base stations include a plurality of transmit antennas and terminals include a plurality of receive antennas to form MIMO channels. In one embodiment, a simulcasting MIMO wireless communication system includes orthogonal frequency division multiplexing (OFDM). This arrangement achieves the spectral efficiency advantages of OFDM and simulcasting.

  • Publication number: 20140050207
    Abstract: An efficient method for providing both dedicated and simulcast services over a common wireless infrastructure is described. The services can be available to a single terminal as well as to a multiplicity of terminals simultaneously. The method uses time division multiplexing and orthogonal frequency division multiple access for simulcasting information and transmitting dedicated message information from a plurality of base stations forming a cellular pattern over the same wireless frequency channel. The method comprises the steps of constructing frames for transmission by the plurality of base stations comprising control information, simulcast information and dedicated message information within predetermined time slots of the frames and allocating the simulcast information and the dedicated message information to time slots of the same frame predetermined by the control information of the frame. The underlying modulation technology used is OFDM and thereby the channel delay-dispersion is minimized.
