Abstract: 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.

Abstract: 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.

Abstract: A power management system and method for a wireless communication device generates an average desired transmit power signal based on at least one of a received signal strength indicator signal and a power control instruction signal from a base station. A power supply level adjustment signal is generated based on the data parameters of an outgoing data stream and at least one environmental information signal. A combination of the power supply level adjustment signal and the average desired transmit power or a gain control signal and an altered version of the power supply level adjustment signal is used to generate a variable power supply signal that is provided to an output amplifier block for sufficiently generating outgoing wireless device radio signals while reducing power loss in the output amplifier block.

Abstract: The settling time of a wireless receiver is reduced by providing a previously utilized gain control state value to an amplifier of a receiver front end during a warm-up portion of a wake-up period of the wireless receiver which follows a sleep period. One illustrative method includes the steps of receiving a notification signal which indicates that the wireless receiver is to be placed in a sleep mode, reading a gain control state value from a gain controller based on receiving the notification signal, storing the gain control state value in memory, providing the stored gain control state value from the memory to the wireless receiver during a warm-up period of a second wake-up period following the first wake-up period, and providing a gain control state value from the gain controller to the wireless receiver based on a signal level of a currently received signal of the wireless receiver after the warm-up period.

Abstract: In accordance with the teachings described herein, systems and methods are provided for battery capacity estimation. A profile table may be used that relates a plurality of battery profile values with a plurality of operating parameter values. The profile table may be accessed to translate one or more measured operating parameters into one or more corresponding battery profile values. One or more of the battery profile values may be adjusted by a correction factor to generate a corrected battery profile value. The available capacity of the battery may be calculated using the corrected battery profile value. The correction factor may then be automatically calibrated by using an estimated battery profile value calculated from the one or more measured operating parameter.
