Digital pre-distortion for multi-antenna systems
Abstract:
Certain aspects of the present disclosure relate to methods and apparatus for power amplifier control. A power amplifier network includes a first path comprising a first power amplifier. The power amplifier network further includes a second path comprising a second power amplifier. The power amplifier network further includes a common input path to both the first path and the second path. The power amplifier network further includes a first power control network for controlling a first signal applied to the first power amplifier. The power amplifier network further includes a second power control network for controlling a second signal applied to the second power amplifier, wherein the first power control network is different from the second power control network.
