Over the past few years, novel waveforms have emerged, such as orthogonal time-frequency space (OTFS), orthogonal delay-Doppler division multiplexing (ODDM), and chirp domain waveforms, such as orthogonal chirp-division multiplexing (OCDM), and affine frequency division multiplexing (AFDM). These waveforms effectively spread the information symbol across broad regions of time and frequency components, hereby offering enhanced diversity performance compared to. In parallel, new variants of OFDM, such as frequency-modulated OFDM (FM-OFDM), have also demonstrated robust error performance against high channel dynamics.

This NEW-SIG will focus on the next-evolution waveform (NEW)-related designs considered as potential candidates for future 6G networks with unprecedented data rate, energy efficiency, mobility, and sensing requirements.
