Experimental evaluation of digital predistortion with FBMC and OFDM signals

In this paper we would like to point out one open issue related with filtered bank multi-carrier signals (FBMC). The experiment was trying to give an answer whether the FBMC signals would keep their beneficial properties even whilst real non-linear power amplifiers were employed. As one of the merits that have been used were error vector magnitude (EVM) and adjacent channel power (ACP). Due to higher sensitivity to angle rotations the digital predistortion have been employed in order to evaluate the importance of linearization.
