This paper presents a Frequency Spreading Filter Bank Multi-Carrier (FS-FBMC) waveform as a potential candidate for the
5th Generation network applications at millimetre-waves (mmWaves). The proposed model is developed based on the Orthogonal
Frequency Division Multiplexing (OFDM) waveform standardized by IEEE 802.15.3c for 60 GHz high data-rate applications. The
effect of non-linearities of Power Amplifiers (PA) at 60 GHz for both OFDM and FS-FBMC are presented and compared using
a realistic PA model. In particular, the sensitivity of both transmission schemes to the non-linear effects is investigated and its
impact on the performance degradation in terms of Output-Power-Backoff (OBO), is characterized over typical indoor Line-Of-
Sight (LOS), kiosk and residential, 60 GHz IEEE channel models. The assessment metrics considered are: Bit Error Rate (BER)
and Out-Of-Band Emissions (OOBEs). This study concludes, radio access schemes for future communication generations, i.e. 5G
may employ OFDM for up-link and FS-FBMC for down-link due to the sensitivity to PA non-linearities of both waveforms.
