ODDM Waveform

Orthogonal Delay-Doppler Division Multiplexing (ODDM)

A novel delay-Doppler domain multi-carrier (DDMC) waveform

    • What is the waveform of ODDM
      • An example of ODDM waveform having M multi-carrier (MC) symbols is shown below, where each MC symbol has N=4 subcarriers and pulse-shaped by the DDOP namely a pulse-train being composed of N sub-pulses. In particular, the sub-pulses are root Nyquist pulses, for example, the root raised cosine (RRC) pulses. As a result, each MC symbol has N sections in time domain,  and then M symbols form an ODDM frame in a staggered manner.oddm_waveform_image
