Performance study of 5G multicarrier waveforms

In the near future some of mobile communication prime objectives need to be improved, including increased capacity, higher data rate, low latency, and better quality of service. To respond to these growing demands, a modification should be done at the physical layer in terms of waveforms adopted. Flexible waveforms have been proposed to meet the challenges faced in current generation systems such as: Filter Bank Multi Carrier (FBMC), Universal Filtered Multi Carrier (UFMC) and Generalized Frequency Division Multiplexing (GFDM). This paper studies 5G waveforms, their advantages for the new generation, analyses their performance and makes a comparison between these waveforms and OFDM.
