Abstract

Enhancing power efficiency and bandwidth of RF
power amplifiers (PAs) is always a challenge for future mobile
basestation transceivers. Linearization, most commonly as a
digital predistortion system (DPD), is essential to enhance power
efficiency of individual transmit paths. Especially massive MIMO
systems for 5G applications and beyond with multiple transmit
paths and PAs are challenging in respect of implementation effort
and resource costs. An individual signal processing block for each
transmit path is a possible but costly solution. This work shows
different solutions for a cost efficient design of a DPD system
for hybrid multi-user mMIMO applications with artificial neural
networks (ANNs).
