Abstract
Disclosed are implementations, including a method for monitoring a performance of a transmitter in a radio with an adjustable digital predistortion system. The method includes determining a plurality of system characteristics, including determining one or more of, for example, data characterizing an input/output characteristic of a digital predistorter of the system, data characterizing a performance of a crest factor reduction process of the system, data characterizing a quality of a plurality of parameters associated with the digital predistorter, data characterizing an average time delay associated with the system, data characterizing an average gain associated with the system, and/or data characterizing a phase associated with the system. The method further includes comparing one or more of the plurality of system characteristics to respective one or more reference values, and controlling the adjustable digital predistortion system based on a result of the comparing.
