SC-FDMA (Single Carrier Freq Domain Multiple Access) used in Up-Link in LTE.
o The system uses SC-FDMA as uplink multiple access method instead OFDMA to decrease the PAPR and power requirements.
o It offers the same degree of multipath mitigation but because the transmission is
on single carrier PAPR is lower.
o The basic idea is to add cyclic prefix to the mapped symbols and in the receiver
multipath distortion can be handled by the same method as OFDM (carrier based equalization).
