- 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.
