Abstract

Single carrier-frequency division multiple access (SC-FDMA) is an OFDMA variant technology that is tailored for uplink transmission. It uses the standard OFDMA transceiver blocks with different ordering. SC-FDMA (aka DFT-precoded/spread OFDMA) is the multiuser version of single carrier modulation with frequency domain equalization (SC/FDE). The main objective of SC-FDMA is to introduce transmission with lower PAPR than OFDMA. Since OFDMA shows envelope fluctuations, and signals with high PAPR requires highly linear power amplifiers to reduce the distortion, the design of mobile terminals are complex and they become power hungry since the linearity in the amplifier can only be handled with a large backoff from their peak power.
