Abstract
This paper proposes a thorough comparison of post-OFDM waveforms with both time and frequency selective channels. The waveforms which are considered are CP-OFDM, f-OFDM, WOLA, WOLA-COQAM, FBMC-OQAM, UF-OFDM, Wavelet-OFDM, FFT-FBMC and BF-OFDM. All these waveforms are potential candidates to support critical machine type communications (C-MTC) typically between devices. Based on real propagation channels, it first appears that UF -OFDM is more sensitive to delay spread compared to the others waveforms which have all similar performance. For large velocities, WOLA-COQAM, FFT-FBMC and BF-OFDM experience error floors much larger than the other waveforms.
