Webauthors introduce a new waveform called frequency-division multiplexing with a frequency-domain cyclic preﬁx (FDM-FDCP). This waveform, at its current stage, outperforms OFDM in channels with high Doppler and low delay spread. However, its performance in channels with high Doppler and medium to high delay spread is yet to be understood, [3].
