Renu Rani, Garima Saini, Anuj Kumar . Peak-to-Average Power Ratio Analysis of SCFDMA Signal by Hybrid Technique. International Journal of Computer Applications. 69, 15 ( May 2013), 26-29. DOI=10.5120/11920-8093
The low peak-to-average power ratio (PAPR) in single-carrier systems has motivated the Long Term Evolution (LTE) Third Generation Partnership Project (3GPP) to adopt single carrier frequency division multiple access (SC-FDMA) as the uplink multiple access scheme. In this paper, an enhancement of a SC-FDMA system by decreasing the PAPR is focused. A combination of clipping and Pulse shaping (RRC filter) is applied on a SC-FDMA signal with IFDMA subcarrier mapping, which results in a PAPR reduction. This PAPR reduction by hybrid (clipping & pulse shaping) technique can be used to enhance the power efficiency of the handset, or alternatively to improve uplink throughput and/or operating range.
