Talk Title: From Theory to Implementation: Realizing Delay-Doppler Domain Multi-Carrier Modulation
Recent advances in wireless communication have highlighted the delay–Doppler domain as a natural representation for time-varying channels. Building on this perspective, delay-Doppler domain multi-carrier (DDMC) modulations, such as orthogonal delay-Doppler division multiplexing (ODDM), introduce a new paradigm that unifies time and frequency resources while ensuring robust performance under high mobility. This talk presents the theoretical foundations, signal structure, and orthogonality principles of DDMC/ODDM, emphasizing their fundamental distinctions from conventional OFDM systems. Key aspects of waveform implementation and receiver filter design are then discussed, highlighting practical considerations for realizing DDMC/ODDM in modern transceivers. The talk aims to offer both conceptual insights and engineering guidelines for researchers seeking to translate delay–Doppler theory into real-world communication systems.
