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.
