Abstract: For single carrier based waveform, Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) and single carrier with a frequency domain equalizer (SC-FDE) can be considered for both DL and UL. For OFDM based transmission scheme including DFT-s-OFDM, a cyclic prefix (CP) is inserted at the beginning of each block, where the last data symbols in a block is repeated as the CP. Typically, the length of CP exceeds the maximum expected delay spread in order to overcome the inter-symbol interference (ISI). For SC-FDE transmission scheme, a known sequence (guard interval (GI), unique word (UW), etc.) can be inserted at both the beginning and end of one block. Further, a linear equalizer in the frequency domain can be employed to reduce the receiver complexity. Compared to OFDM, SC-FDE transmission scheme can reduce Peak to Average Power Ratio (PAPR) and thus allow the use of less costly power amplifier.
