It is used in satellite communication systems and telephone trunklines . FDMA splits the total bandwidth into multiple channels. Each ground station on the earth is allocated a particular frequency group (or a range of frequencies).
Read moreWhy SC-FDMA is single carrier?
SC-FDMA (Singe Carrier FDMA) presents the benefit of a single carrier multiplexing of having a lower Peak-to-average Power Ratio . On SC-FDMA before applying the IFFT the symbols are pre coded by a DFT (Discrete Fourier Transform). This way each subcarrier after de IFFT will contain part of each symbol.

Direct Fourier Transform spread OFDM, commonly abbreviated to DFT-s-OFDM, is an SC or single carrier-like transmission scheme that can be combined with OFDM that gives significant flexibility for a mobile communications system like 5G. It is more commonly known as SC-FDMA .
Read moreWhy SC-FDMA is used in?
SC-FDMA is preferred for LTE uplink mainly due to its advantage of having low peak-to-average power ratio (PAPR) during signal transmission. The performance of SC-FDMA depends on modulation scheme used for it.
