Abstract

In this paper we present a reduced complexity digital
predistortion of multiple power amplifiers. The reduction is based
on using only one feedback path taking into account the similar
characteristics of amplifiers in the MIMO system. After some
theoretical basics, the paper presents the results of the experiment
trying to give an answer whether the predistortion can be used
with limited (in extreme case with only one) number of feedback
paths. Due to its very low out-of-band emissions, the filter-bankmulticarrier
signal has been used as a test signal as a typical
representative of post-OFDM waveforms.
