Arjun Solanki, Ratna Gour . Performance Assessment of PAPR in OFDM System using Single Carrier - FDMA. International Journal of Computer Applications. 94, 19 ( May 2014), 39-44. DOI=10.5120/16502-6189
Abstract
Orthogonal frequency division multiplexing (OFDM) is a promising multicarrier modulation technique for high data rate communication. Unless, OFDM faces the peak-to-average-power ratio (PAPR) problem that is a major drawback of multicarrier transmission system which leads to power inefficiency of high power amplifier (HPA) and also demands the large dynamic range of digital to analog converter (DAC) at the transmitter. A number of schemes have been proposed to reduce the PAPR problem. The Discrete Fourier Transform (DFT) Spreading is one of the scheme to reduce the PAPR Problem in OFDM system. This paper presents the DFT spreading technique to reduce the PAPR problem. The PAPR reduction capability of this technique is demonstrated by presenting simulation results of PAPR.
