Abstract [en]
In this paper we evaluate the effect of applying peak-to-average power ratio (PAPR) reduction and digital pre-distortion (DPD) on RF power amplifiers when an OFDM signal is used. The cases where PAPR and DPD are applied separately and combined, are studied and investigated. Good performance is shown when combining both pre-processing techniques up to a certain operating point where DPD performance deteriorates. Solutions to improve the DPD performance at strong compression are suggested.
