2-D Digital Predistortion (2-D-DPD) Architecture for Concurrent Dual-Band Transmitters

IEEE Transactions on Microwave Theory and Techniques, 2011
This paper presents a novel 2-D digital-predistortion (2-D-DPD) technique that is applicable for linearization of concurrent dual-band transmitters. This technique uses a unique way for distortion compensation and linearization of dual-band transmitters by selecting, characterizing, and applying predistortion in each band separately.

Closed-Loop Digital Predistortion (DPD) Using an Observation Path With Limited Bandwidth

IEEE Transactions on Microwave Theory and Techniques, 2015
This paper shows that digital predistortion (DPD) used to linearize an RF power amplifier (PA) can achieve wide bandwidth distortion cancellation using measurements obtained from a narrow bandwidth observation path. The DPD module creates a correction signal using a set of nonlinear basis waveforms, weighted by adjustable coefficients. The coefficients
