Abstract

The paper proposed a novel channel multiplexing scheme, in which the fractional Fourier transform (FRFT) domain channel division takes the place of traditional time- or frequency-division. With the help of proper signal design, the time-frequency aliasing is eliminated by FRFT domain filtering. The simulation results show that the proposed scheme will reduce the inter symbol interference and improve the bit error ratio performance compared to the single channel scheme with the same bit rate.
