    摘要: The wireless communication device includes a wireless communication transceiver to generate an oscillator control signal and an activation signal, a positioning-system receiver (e.g. a GPS receiver) to process received positioning signals, and a shared oscillator (e.g. a temperature compensated and voltage controlled crystal oscillator TCVCXO) responsive to the oscillator control signal and to generate a reference frequency signal for the wireless communication transceiver and the positioning-system receiver. The positioning-system receiver may control processing of the received positioning signals based upon the activation signal to reduce a noise contribution (e.g. phase noise) due to frequency control of the shared oscillator based upon the oscillator control signal. The activation signal may indicate that the oscillator control signal is being varied to provide frequency control or adjustment of the shared oscillator.

    摘要: A peak to average power ratio signal is generated from a first mapping function that selects the peak to average power ratio signal that corresponds to the data rate or data format of the signal to be transmitted. The selected peak to average power ratio signal is summed with a desired average transmit power signal. The resulting summation signal is input to a second effectively continuously valued mapping function comprising a table that has a plurality of power amplifier control signal values each with a corresponding peak transmit power. Each peak transmit power signal value results in a power amplifier control signal value that achieves the best possible transmitter power efficiency while still meeting out of band spurious emissions and waveform quality requirements. The summation signal value maps to one of the power amplifier control signal value that is then used to adjust a parameter such as bias of the power amplifier.

    摘要: A method includes steps, performed by a wireless device for accessing a wireless network through network base stations. The steps include selecting a reverse link cost metric from a list of reverse link cost metrics. A reverse link cost is determined according to the selected reverse link cost metric. A plurality of base stations are partitioned into a plurality of candidate base stations and a plurality of excluded base stations. The plurality of base stations are substituted with the candidate base stations, thereby reducing the cardinality of the plurality of base stations by the cardinality of the plurality of excluded base stations. A candidate base station is selected from a plurality of the base stations. A probe signal is sent at the reverse link cost to the candidate base station. A response from the candidate base station is waited for within a timeout period.
