摘要：According to the further increase of demand on high data rates in wireless communications systems, the 4th generation (4G) of mobile telecommunication networks have been introduced by 3GPP (3rd Generation Partnership Project). These systems have adopted orthogonal frequency division multiplexing access (OFDMA) for downlink physical layer and single carrier frequency division multiple access (SCFDMA) for uplink physical layer. In this paper, SC-FDMA is simulated and analyzed for all the parameters and for various modulation index of phase shift keying. This research also focused on the calculation of Peak- to-Average Power Ratio (PAPR) for SC-FDMA. Finally, a performance evaluation for SC- FDMA implemented with different conditions are perform to show the effect of the data symbol duration and FFT (Fast Fourier Transform) size on the uplink physical layer of the 4G.
