To overcome the effect of multi path fading problem available in UMTS, LTE uses Orthogonal Frequency Division Multiplexing (OFDM) for the downlink – that is, from the base station to the terminal to transmit the data over many narrow band careers of 180 KHz each instead of spreading one signal over the complete 5MHz …
Read moreWhat type of modulation is used in cell phones?
Most radio systems and handsets use FM analog modulation that occupies a 25-kHz channel.
Read moreWhich path used SC-FDMA in LTE?
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
