    摘要: One method of estimating timing and frequency information of a payload transmitted through two or more frequency separated channels combines training fields from preambles from the two or more frequency separated channels to construct combined values that may be used to estimate the frequency and timing information. In one embodiment, the combined values may be determined by combining self-correlated training fields from the frequency separated channels. Another method of estimating the timing and frequency information selects the training fields from the preamble of one of the frequency separated channels based upon a signal quality metric. In another embodiment, the selection of the training fields based upon a signal quality metric may be biased to favor a particular channel.

    摘要: A software license for a particular version of a software product on a computing device includes both a branding identifier that identifies the particular version of the software product and component dependency information that identifies one or more aspects of the particular version of the software product. To activate a software product on the computing device, the branding identifier is compared to a portion of the software product on the computing device. If the branding identifier matches the portion of the software product, then the component dependency information is compared to one or more aspects of the software product on the computing device. If the component dependency information matches the one or more aspects of the software product then the software product is activated. Otherwise, the a license state of the software product is kept unchanged.

    摘要: Systems, apparatus and methods for determining a cyclic shift diversity (CSD) mode are presented. Examples use two different autocorrelations to determine a current CSD mode. Specifically, a delay-based autocorrelation and a cyclic shift-based autocorrelation are each computed then compared to each other, for example, by taking a difference of the two autocorrelations. A multipath signal leads to similar autocorrelations, where as a signal with a CSD mode enabled leads to dissimilar autocorrelations. By examining the number of peaks in the delay-based autocorrelation or the autocorrelation difference, a current CSD mode may be determined.

    摘要: A mobile station is configured to authenticate applications running thereon in order to control access by the authenticated applications to secure data stored in a subscriber identity module of the mobile station. Sensitive data securely stored in the subscriber identity module is associated with one of multiple personas implemented on the mobile station. When an application running on the mobile station requests access to the secure data, a secure domain controller processes the request and authenticates the application, for example based on an application authentication key. The secure domain controller further determines whether the application is associated with the same persona as the secure data identified in the request. If the application is authenticated, the secure domain controller then allows the application to access secure data associated with the same persona, but prevents the application from accessing secure data associated with other personas.

    摘要: Functionality can be implemented for automatic gain control (AGC) in a wireless network device to determine whether to change the gain of the wireless network device based on determining the strength of an RF signal. At various time instants, the strength of the RF signal can be compared against different thresholds to determine the presence of and severity of the saturation of the RF front end. The gain settings can be adjusted based on comparing the strength of the RF signal with a set of thresholds. This can help the wireless network device receive RF signals with little or no distortion, and can minimize RF saturation, gain compression, false detection and other performance degradation at the wireless network device.

    摘要: A receiver for a wireless communication device comprising a mechanism for performing spur mitigation. A spur mitigation unit of the receiver is operable to determine a current estimate of a spur signal from an ADC output signal using a growing box filter. The spur mitigation unit can determine a power of the current estimate of the spur signal and a power of a previous estimate of the spur signal using a power measurement unit. The spur mitigation unit can determine whether the power of the previous estimate of the spur signal is greater than the power of the current estimate of the spur signal. If the power of the previous spur signal estimate is greater than the power of the current spur signal estimate, the spur mitigation unit can remove the spur signal from the ADC output signal based on the previous spur signal estimate.
