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 moreWhy we are using SC-FDMA in LTE uplink instead of OFDMA?
The performance of SC-FDMA in relation to OFDMA has been the subject of various studies. Although the performance gap is small, SC-FDMA’s advantage of low PAPR makes it desirable for uplink wireless transmission in mobile communication systems, where transmitter power efficiency is of paramount importance .
Read moreWhy OFDMA used in downlink and SC-FDMA for uplink?
OFDMA is used on the downling, but since it presents a high Peak-to-average Power Ratio it is not possible to use it on the uplink . For the uplink SC-FDMA will be used.
Read moreWhich modulation technique is used in LTE for uplink transmission?
While LTE’s downlink uses OFDM, the uplink uses a different modulation scheme known as single-carrier frequency-division multiplexing (SC-FDMA) . OFDM signals have a high peak to average power ratio (PAPR), requiring a linear power amplifier with overall low efficiency.
