DFT-s-OFDM 6G

Technical Explanation

DFT-spread-OFDM applies a Discrete Fourier Transform before subcarrier mapping to reduce PAPR. In 6G, DFT-s-OFDM is enhanced with frequency-domain spectral shaping (FDSS) and dynamic zero-padding. This further reduces PAPR down to near 0 dB, allowing compact user devices to transmit high-speed data to base stations across Sub-THz frequencies without overheating or rapidly draining batteries.

Key Functions

• Further reduction of PAPR down toward 0 dB via frequency-domain spectral shaping
• Maximizing uplink transmission power from handheld user devices and wearable AR glasses
• Eliminating spectral splatter and out-of-band emissions into adjacent frequency channels
• Flexible resource block allocation compatible with standard 6G base station receivers
• Essential physical layer mode for battery-constrained mobile 6G uplink transmissions
