Evaluation of Waveform Candidates for 5G Wireless Communications [PDF]

, 2019
In this paper, we evaluate the waveform candidates for 5G wireless communications such as FBMC and UFMC and 4G’s cyclic prefix CP-OFDM. Measured results for 1.4 MHz and 3 MHz waveforms show a 5 dB reduction in ACPR between FBMC and UFMC.
