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 moreWhat is the advantage of OFDMA over conventional FDMA?
SC- FDMA has a lower PAPR and lower sensitivity to carrier frequency errors while OFDMA provides better frequency diversity resulting in better immunity against multipath fading .
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 advantage of using SC-FDMA in the uplink?
SC-FDMA has drawn great attention as an attractive alternative to OFDMA, especially in the uplink communications where lower peak-to-average power ratio (PAPR) greatly benefits the mobile terminal in terms of transmit power efficiency and reduced cost of the power amplifier .
Read moreWhat is the advantage of FDMA over TDMA and FDMA?
Benefits or advantages of OFDMA Hence OFDMA makes efficient use of frequency allocations in comparison to FDMA and OFDM. ➨It provides multi-user diversity. This is due to the fact that OFDMA allows different users to transmit over different parts of the frequency spectrum known as traffic channel.
Read moreWhat is SC-FDMA in LTE?
SC-FDMA is a hybrid modulation scheme that combines the low peak-to-average ratio (PAR) of traditional single-carrier formats such as GSM with the multipath resistance and in-channel frequency scheduling flexibility of orthogonal frequency-division multiplexing (OFDM). Acronyms galore: LTE history and context.
