Abstract: Systems and methods for use in configuring a power amplifier system are provided. The method includes generating a phase error compensation signal using a phase error model configured to determine the phase error compensation signal based at least in part on an amplitude and a phase of an input signal for the power amplifier system. The phase error model is configured to estimate a time and frequency-dependent phase error in a power amplifier output signal associated with the amplitude and the phase of the input signal, and the phase error compensation signal is configured to at least partially correct the time and frequency-dependent phase error in the power amplifier output signal. The method further includes applying the phase error compensation signal to the input signal to generate a corrected input signal and providing the corrected input signal to the power amplifier system.

Abstract: A method uses a set of reference symbols. The method includes receiving a first symbol, comparing the first symbol to the set of reference symbols, and selecting a reference symbol from the set of possible reference symbols. The set of reference symbols are adjusted by a set of respective error factors for each of the reference symbols. The reference symbol is selected when it matches the first symbol. The method also includes adjusting the respective error factor for the reference symbol in accordance with a difference between the first symbol and a remodulated reference symbol in one embodiment.

Abstract: A two-way paging system (10) includes a plurality of personal paging units (16). The personal paging units (16) receive pages (18), and generate radio signals (28) in response to the pages. The system includes a transmitter (12) for generating the pages, and a receiver (14). The receiver includes first and second receiving circuitry (30) and (34). The first receiving circuitry receives radio signals from the personal paging units. The second receiving circuitry receives radio signals from a source other than the personal paging units. The receiver further includes a data processor (32) electronically linked with the first and second receiving circuitry in the receiver. The data processor determines the time period during which radio signals are received from the personal paging units by the first receiving circuitry, based on radio signals received from the other source by the second receiving circuitry. In a preferred embodiment, the second receiving circuitry receives radio signals from the transmitter.
