A novel digital predistortion technique for class-E PA with delay mismatch estimation

Abstract

This paper proposes a polynomial-based adaptive digital predistortion (DPD) method with delay mismatch estimation for the class-E power amplifier (PA), which can compensate the AM-AM and the strong AM-PM distortion produced by the switching operation of class-E PA. On the other hand, due to the strict requirement of timing alignment in polar transmission, a… (More)
