Owing to its inherent single carrier structure, a prominent advantage of SC-FDMA over OFDM and OFDMA is that its transmit signal has a lower peak-to-average power ratio (PAPR) , resulting in relaxed design parameters in the transmit path of a subscriber unit.
Read moreWhat is the difference between OFDM and SC-FDMA?
The most obvious difference between the two schemes is that OFDMA transmits the four QPSK data symbols in parallel, one per subcarrier, while SC-FDMA transmits the four QPSK data symbols in series at four times the rate , with each data symbol occupying a wider M x 15 kHz bandwidth.

5G Cellular Technology Tutorial Includes: OFDM gives good spectral efficiency whilst providing resilience to selective fading and it also enables multiple access capability to be implemented using OFDMA .
Read moreDoes 5G use SC FDMA?
Unlike LTE, 5G NR also supports CP-OFDM in the uplink direction. But LTE’s discrete Fourier transform spread OFDM (DFT-s-OFDM) uplink scheme, better known as single carrier frequency division multiplex (SC-FDMA), is still a valid access scheme and support is mandatory for any 5G terminal.
Read moreWhat is OFDM numerology?
OFDM numerology design for wide range of carrier frequencies, deployment types, and application latency requirements using regular slots . 100 GHz. Frequency. 15 kHz. 30 kHz.

If your phone has a 5G modem, you will see one of two symbols: 5G or 5G+. 5G means your phone is currently connected to 5G NR on a sub-6 GHz frequency . Bands in this range provide better coverage but slower speeds. The higher the frequency, the faster your download speeds.
Read moreHow do you find the number of subcarriers in 5G?
Number of subcarrier per PRB is 12 . Number of OFDM symbols per slot may vary depending on subcarrier spacing. For subcarrier spacing <= 60, the number of OFDM symbols / slot = 7 or 14. For subcarrier spacing > 60, the number of OFDM symbols / slot = 14.
