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
• 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 (Multiple Input Multiple Output).
• They are like Gold sequences as used in PDSCH.
• CP-OFDM offers very high spectral packing efficiency in RBs (Resource blocks). It is employed when network operators need to maximize network capacity in dense urban environments.
5G NR 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 as used in LTE uplink.
• It is used for power limited scenario.
• It is only used in single layer transmission.
• They are like Zadoff chu sequences used in uplink.
• Though it offers less efficient spectral packing, it is used to address greater range requirements.
