Abstract
A new adaptation technique for digital predistortion is presented. The proposed method employs the real-time input and output signals of a high power amplifier (HPA) to estimate the complex envelope transfer characteristics. Therefore, a look-up table update can be performed without Interrupting the normal transmission of messages through an HPA
