...Compared to orthogonal frequency division multiplexing (OFDM) [5], single-carrier (SC) with frequency domain equalization (FDE) [6,7] has similar performance and complexity but much lower PAPR, which relaxes requirements on power-amplifier linearity and thus enables the use of more efficient and cheaper amplifiers....

...Since OFDM suffers from high peak-to-average power ratio (PAPR) problem, SC techniques leading to more efficient use of power amplifiers are more suitable for uplink channels [1], [2]....

...It has been shown in [1] that frequency domain equalization (FDE) can readily be applied to SC transmission to yield similar performance to OFDM....
