Influence of Filter-Bank RF transceiver chain imperfections on digital predistortion performance

Novel multicarrier waveforms, such as, Filter Bank Multi Carrier promise lower out-of-band emissions compared to the currently used Orthogonal Frequency Division Multiplex technique. Unfortunately, the power amplifier nonlinearity in the transmitter can significantly degrade the FBMC spectrum wiping-out the differences between these two approaches. In order to compensate for nonlinearities and memory effects introduced by power amplifiers, the digital predistortion is a widely used technique, but also the predistortion itself can significantly be influenced by the transceiver imperfections. This paper thus laid great emphasis on the evaluation of transceiver imperfections and uncertainties on the overall performance of digital predistortion driven with FBMC signals.
