Abstract
A radio frequency (RF) transmit system includes an observation receiver coupled to receive a portion of an RF signal propagating along an RF transmit signal path and a digital pre-distortion (DPD) system coupled to the observation receiver and configured to receive one or more signals from the observation receiver and in response thereto, to adapt one or more DPD values of the RF transmit system over a period of time and a range of operating conditions of the RF transmit system and to provide one or more adapted DPD values to said controller.
