M.V.R. Vittal . PAPR Reduction of Single Carrier FDMA Signals using Efficient SINC Pulse Shaping. International Journal of Computer Applications. 186, 25 ( Jun 2024), 40-44. DOI=10.5120/ijca2024923763
Orthogonal frequency division multiplexing (OFDM) system is one of the important multicarrier modulation techniques that satisfies the need for high spectral efficiency and good quality of service. It is an efficient candidate for supporting the current 5G technology and aims at achieving high data rate in wireless communications. Single carrier FDMA (SC-FDMA) system has equal performance and the complexity matches to that of OFDM. But high Peak to average power ratio (PAPR) is an issue that increases the complexity of analog to digital converters. In this paper, Localized FDMA(LFDMA), Distributed FDMA(DFDMA) and Interleaved FDMA(IFDMA) schemes are discussed and the PAPR analysis of SC-FDMA signals using Raised cosine and Sinc pulse shapings is carried out and their performance is compared.
