CP-OFDM vs DFT-S-OFDM | Difference between CP-OFDM and DFT-S-OFDM waveforms in 5G

This page compares CP-OFDM vs DFT-S-OFDM waveforms used in 5G NR and mentions difference between CP-OFDM and DFT-S-OFDM waveforms used in 5G NR downlink and uplink chains.


5G NR CP-OFDM chain

CP-OFDM Chain

• The figure-1 depicts CP-OFDM waveform. It is used in downlink and uplink chains in physical layer of 5G NR system.
• It is used for high throughput scenario.
• It is intended for MIMO.
• They are like Gold sequences as used in PDSCH.

5G NR DFT-s-OFDM chain

DFT-s-OFDM chain

• The figure-1 depicts DFT-s-OFDM waveform. It is used in uplink chain in physical layer of 5G NR system.
• It is used for power limited scenario.
• It is only used in single layer transmission.
• They are like Zadoff chu sequences used in uplink.
