DFT-s-OFDM
A single carrier-based transmission scheme is utilized in the uplink of LTE and 5G NR wireless systems. It is similar to single carrier frequency division multiple access (SC-FDMA), where each user or transmitter is allocated a single carrier and a finite portion of the channel bandwidth, and every user is separated from the adjacent users with a finite amount of spacing to prevent interference. See also OFDM.
