Abstract
This paper evaluates the peak-to-average power ratio (PAR) performance of a multicarrier system based on the fractional Fourier transform (FRFT). Analytical evaluation and simulations verify that this system, which greatly outperforms classical OFDM system in rapidly fading channels, can also provide a better PAR performance in some situations. In addition, further PAR reduction can be obtained by applying the well-known selective mapping method (SLM)
