Digital predistortion in varying operating conditions

摘要: Disclosed are digital predistortion implementations, including a method that includes collecting data for wireless device with transmit chain at least one power amplifier produces output non-linear distortions, the records each input signal and corresponding chain, record being associated set of operating conditions values, variety measure representative an extent distinguishability from other records. The further selecting some according to criterion computed based on record, computing, selected records, parameters used control predistorter device, applying predistorter, configured parameters, subsequent signals.
