  • This paper gives the discrete Fourier transform (DFT) implementation of the overlapped frequency division multiplexing (OvFDM) of non-orthogonal frequency division multiplexing (NOFDM) systems. This paper investigates the impact of conventional cyclic-prefix and zero-padding cyclic-prefix for DFT-OvFDM/DFTNFODM systems in the time-variant frequency-selective fading channels, respectively. Theoretical analysis and simulation results show that the zero-padding cyclic-prefix can exploit much more frequency diversity than the conventional cyclic-prefix.
