Uplink OFDM Modulation
OFDM modulator, demodulator and dimension information
5G NR uplink transmission uses orthogonal frequency division multiplexing (OFDM) modulation. Additionally, you can use transform precoding together with OFDM modulation to create a single-carrier frequency division multiple-access (SC-FDMA) or DFT-s-OFDM waveform.
