“…Besides the advantage of manageable inter‐symbol interference (ISI) for multi‐carries technologies, FBMC also has higher spectral efficiency [1–4]. However, the FBMC signal is sensitive to non‐linear channel distortion due to the high peak‐to‐average power ratio (PAPR), preventing its development in satellite communications [5, 6].…”

The filter bank multicarrier (FBMC) with offset quadrature amplitude modulation (OQAM) is one of the alternative modulation schemes to orthogonal frequency division multiplexing for next generation broadband wireless access systems. The non-linearity of high-power amplifiers (HPA) has a crucial effect on the performance of FBMC systems. In this study, the impacts of non-linear distortion effects are considered in a FBMC-OQAM system when the signal is passed through a HPA for mediumand high-power signals which are modelled as amplitude and phase distortions. Specifically, memory-less HPA non-linear distortion models such as solid-state power amplifier (SSPA), soft-envelope limiter (SEL), travelling wave tube amplifier are proposed for FBMC systems. A closed-form expression for bit error rate expression is derived and analysed for SSPA and SEL models for FBMC/OQAM system with non-linear HPA in frequency-selective Rayleigh channel by varying constellation size in OQAM modulation and input back-off. The performance is compared for the models with 64 sub-channels and input back-off for 6 and 8 dB. In lieu of validating the obtained simulation results, theoretical results are being compared.

“…In [11], the authors have investigated the bit‐error‐rate (BER) performance of FBMC‐OQAM in the presence of phase error using the discrete probability distribution of the intrinsic‐interference. This investigation was limited to 4‐OQAM constellation and additive white Gaussian noise (AWGN) channel.…”
