Abstract
A single carrier frequency division multiple access (SC-FDMA), is a technique that has a similar performance and essentially the same overall complexity as those of orthogonal frequency division multiple access (OFDMA). The main advantage of SC-FDMA over OFDMA is its lower peak-to-average power ratio (PAPR). In this paper, an enhancement of a
SC-FDMA by decreasing the PAPR is addressed. An efficient repeated clipping and filtering (RCF) algorithm is applied to a SC-FDMA system, which results in a significant PAPR reduction. System performance remains the same after applying the RCF algorithm. Simulations show the proposed scheme provides a bit error as that of the conventional system. That is, due to the selection of the optimum clipping ratio (CR). For more accurate validation, simulations of the conventional system and the proposed system have been performed using different types of channels. The proposed scheme provides a PAPR reduction by a gain of approximately 4 dB with a slight increase of complexity.
