    • A method for wireless communication is described. A primary radio frequency integrated circuit (RFIC) supporting a plurality of radio frequency (RF) receive paths is provided. Standalone RF resources of a core-resource RFIC to integrate with the plurality of RF receive paths of the primary RFIC to enable an additional functionality of the primary RFIC are then added. A minimum set of RF resources necessary to add support for an additional RF receive path may be determined, and RF resources, including one or more of an antenna, an RF front end, and a low-noise amplifier (LNA) and switches of the primary RFIC, may be shared. A digital baseband integrated circuit (IC), i.e. a modem, may be operated to support both a first of the plurality of RF receive paths from the primary RFIC and a second of the plurality of RF receive paths from the core-resource RFIC.

    • A device may use enhanced power amplifier (PA) linearization techniques such as adaptive feed-forward (FF) linearization using adaptive filters. In one example, an adaptive feed-forward linearizer may isolate a distortion signal based at least in part on the signals input to and output from a PA in a transmission path. The distortion signal may be used to cancel distortion at the output of the PA to produce an improved output signal. A first adaptive circuit may be used to produce the distortion signal and a second adaptive circuit may be used to produce an error cancellation signal based at least in part on the distortion signal. The error cancellation signal may be amplified and re-introduced to the transmission path to produce the improved output signal. Semi-adaptive circuits may be used in place of the adaptive circuits, or a hybrid approach may be used.
    • 设备可以使用增强型功率放大器(PA)线性化技术,例如使用自适应滤波器的自适应前馈(FF)线性化技术。 在一个示例中,自适应前馈线性化器可以至少部分地基于输入到传输路径中的PA并从其输出的信号来隔离失真信号。 失真信号可用于消除PA输出端的失真,以产生改进的输出信号。 可以使用第一自适应电路来产生失真信号,并且可以使用第二自适应电路来至少部分地基于失真信号来产生误差消除信号。 误差消除信号可以被放大并被重新引入到传输路径以产生改进的输出信号。 可以使用半自适应电路来代替自适应电路,或者可以使用混合方式。
