Abstract :
Orthogonal frequency division multiplexing (OFDM) is a prominent technique for providing high Quality of service (QOS) to the users by mitigating the fading of signals and also for providing high data rates in multimedia services. Single carrier FDMA (SC-FDMA) system has similar performance and the same overall complexity as that of OFDM. But Peak to average power ratio (PAPR) is a technical challenge which reduces the efficiency of RF power amplifiers. In this paper, we describe the Localized FDMA(LFDMA), Distributed FDMA(DFDMA) and Interleaved FDMA(IFDMA) techniques and perform the PAPR analysis of SC-FDMA signals using raised cosine and Gaussian pulse shapings and compare the performance.
