Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is a well-known modulation technique for transmission of large amount of digital data with high data rate in both wired and wireless communication systems. High peak-to-average power ratio (PAPR) is the main problem of OFDM system which can be improved by using single carrier frequency division multiple access (SC-FDMA) technique. The simulation results show better performance of the proposed scheme than the existing technique. In this paper, we have analyze the PAPR reduction performance of single carrier frequency division multiplexing (SC-FDM ) with QPSK and 16 QAM modulation and also compare PAPR performance of OFDMA,DFDMA,LFDMA and IFDMA with and without pulse shaping.

Keywords: Orthogonal frequency division multiplexing, Peak to average power ratio. Location based frequency division multiple access, interleaved frequency division multiple access.
