    • Linearizers can improve the linearity of power amplifiers by canceling or reducing amplitude of non-linearity components, (e.g., IM3, IM5, IM7, IM9, etc.) generated by the power amplifier. The linearizers can obtain samples of signals output by the power amplifier and process the samples to produce a compensation signal that is applied onto or into a transmission path leading to the power amplifier's input. The compensation signal is generated such that when amplified by the power amplifier, the amplified compensation signal cancels or reduces at least a portion of the non-linearity components produced by the power amplifier. A controller can improve the correction of the non-linearity components by executing one or more calibration algorithms and/or one or more tuning algorithms and adjusting settings of the linearizer based on the results of the algorithm(s).
    • 线性化器可以通过消除或减小由功率放大器产生的非线性分量(例如,IM3,IM5,IM7,IM9等)的振幅来提高功率放大器的线性度。 线性化器可以获得由功率放大器输出的信号的样本,并处理样本以产生施加到通向功率放大器的输入的传输路径上的补偿信号。 产生补偿信号,使得当由功率放大器放大时,放大的补偿信号抵消或减少由功率放大器产生的非线性分量的至少一部分。 控制器可以通过执行一个或多个校准算法和/或一个或多个调谐算法并基于算法的结果来调整线性化器的设置来改善非线性分量的校正。

    • A communication system and method include a server hosting an interactive voice response or self-help application in a Java virtual machine. The communication application is programmed with a unified communication API, which is provided by a unified application framework. The API provides a set of unified class objects for call control and media control. The unified class objects are constructed from class object primitives of individual standards-based Java call control API and media control API. The constructs are a structured and restricted set conforming to the object model of the application and its states. The API has a unified event handler for both call and media controls and dispatches events to the application based on the type of event and the application state of the object model.
