Global Power Amplifier Efficiency Evaluation with PAPR Reduction Method for Post-OFDM Waveforms

Abstract

This paper provides simulation results to establish a realistic power budget of a transmitter by taking into account different post-OFDM waveforms along with a non linear high power amplifier (HPA). The waveforms used are the Orthogonal Frequency Division Multiplexing (OFDM), the weighted overlap and add OFDM (WOLA-OFDM) and Block-Filtered OFDM (BF-OFDM) coupled with a Peak to Average Power Ratio (PAPR) method (SeLected Mapping) so as to increase the HPA efficiency. Simulation results show that there is a clear optimum point between the PAPR reduction gain and the overall power budget of the transmitter.
