SC-FDMA is widely used in LTE subscriber terminals in the transmit path and variant OFDMA is used in the eNodeB downlink(or receive path of LTE subscriber).
Read moreDoes LTE use FDMA?
As a result, LTE uses a modulation scheme known as SC-FDMA – Single Carrier Frequency Division Multiplex which is a hybrid format.
Read moreWhy SC-FDMA is used in LTE?
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.17 Şub 2020
Read moreWhat is the purpose of using SC-FDMA?
The main objective of SC-FDMA is to introduce transmission with lower PAPR than OFDMA .

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.
Read moreWhere is FDMA used?
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.
