Abstract The performance of a fractional orthogonal frequency division multiplexing (FrOFDM) system is examined considering spectral efficiency (SE). While FrOFDM can reduce peak-to-average power ratio, which is a drawback in OFDM, its bandwidth is expanded. Simulations were performed to evaluate the increasing amount of transmission distance from the signal-to-noise ratio of the received signals with keeping the best SE of OFDM. Simulation results show that FrOFDM can increase the transmission distance without reducing SE.
