Behavioral modeling for digital predistortion of RF power amplifiers: from Volterra series to CPWL functions

摘要

This paper gives an overview of behavioral modeling for digital predistortion of RF power amplifiers. It starts with discussing the specific system requirements and then explains what constraints must be satisfied when developing behavioral models for this application. Both theoretical aspects and practical implementation issues are discussed. Historical development and recent innovation are reviewed with a conclusion of future outlook in the end.
