Linearization of Microwave Emitters using an Adaptive Digital Predistorter

27th European Microwave Conference, 1997, 1997
Adaptive digital predistortion for nonlinear power amplifier (PA) became one of the most robust linearization techniques that can be implemented in digital signal processors (DSP) environment. However, its precision compensation for AM-AM and AM-PM distortion is wasted when the quadrature modulator (QM) impairments are not to be considered.

Concurrent dual-band digital predistortion

2012 IEEE/MTT-S International Microwave Symposium Digest, 2012
With a power amplifier (PA) being able to support widely separated frequency bands, dual-band digital predistortion techniques have been proposed as an efficient alternative to traditional wideband digital predistortion by only compensating nonlinear distortions around the signal bands of interest.

Evolutionary Multiobjective Optimization for Digital Predistortion Architectures

2016
In wireless communication systems, high-power transmitters suffer from nonlinearities due to power amplifier (PA) characteristics, I/Q imbalance, and local oscillator (LO) leakage. Digital Predistortion (DPD) is an effective technique to counteract these impairments.

Digital predistortion for power amplifiers

The power amplier (PA) is one of the most critical subsystems in wireless (and wired) trans- mitters. Not only is it one of the most power hungry devices that accounts for most of the direct current (DC) power consumed in macro base stations, but also it is the main source of nonlinear distortion in the transmitter.
