Abstract:
Systems and method for improving operation of a radio frequency system are provided. One embodiment includes instructions to execute a coarse calibration to associate a first output power with a first operational parameter set; instruct the radio frequency system to transmit a signal based at least in part on the first operational parameter set and a base detrough function; determine performance metrics resulting from transmission of the signal; determine changes in the performance metrics resulting from operating the radio frequency based at least in part on the first operational parameter set and each of a plurality of augmented detrough functions; and associate a second operational parameter set with a second output power, in which the second operational parameter set includes one of the plurality of augmented detrough functions selected based at least in part on the changes that reduce margin between the performance metrics and performance metric thresholds.
