WebThis waveform is also referred to as single-carrier FDM waveform (SCFDM) in the literature. In 3GPP 5G NR, QAM modulation symbols with modulation order (4, 16, 64, 256) can be transmitted using the DFT-s-OFDM. When compared to LTE, a new modulation scheme, namely, π 2 -BPSK was introduced in 5G NR. This is a special constellation-rotated … WebIt is because the time domain symbols have lower PAPR than the frequency domain symbols. The PAPR of OFDM is due to the 2 reasons.
