Papr reduction in SC-FDMA via a novel combined pulse-shaping scheme
Peak-to-average-power-ratio (PAPR) is an important parameter that affects the cost of end-user devices in next generation wireless networks. When PAPR is high, the end-user power amplifier's dynamic range should also be high, resulting in costly power amplifiers. Single-carrier frequency-division-multiple-access (SC-FDMA) is used as the air-interface in LTE-Advanced, and this paper proposes a novel and efficient technique for PAPR reduction via pulse shaping for interleaved-FDMA (IFDMA) subcarrier mapping in SC-FDMA. By way of simulations, we show that PAPR can be reduced by 2.11 dB for our novel pulse shaping compared to raised cosine (RC) pulse shaping with QPSK modulation.
