Originální abstrakt
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.
