Analytical Analysis of SER for Beyond 5G Post-OFDM Waveforms in Presence of High Power Amplifiers

This paper studies the performance of enhanced multicarrier waveforms in the presence of a nonlinear memoryless high power amplifier (HPA). In particular, we focus on the in-band non-linear distortions (NLD) and their effects on symbol-error-rate. First, we introduce a theoretical characterization of NLD caused by HPAs. Two HPA models are considered in this paper: 1) a 4-GHz realistic HPA, modeled using a polynomial model, and this model...
