Abstract: Future wireless networks are expected to provide high-speed and ultra-reliable communications for a wide range of emerging mobile applications, including online gaming, vehicle-to-everything (V2X), and high-speed railway systems. Communications in high mobility scenarios suffer from severe channel Doppler spreads, which deteriorate the performance of the widely adopted orthogonal frequency division multiplexing (OFDM) modulation in the current fourth-generation (4G) and fifth generation (5G) networks. Recently, delay-Doppler domain modulation schemes – including the popular orthogonal time frequency space (OTFS), and the orthogonal delay-Doppler division multiplexing (ODDM) – have been proposed to address the challenges of waveform design for such LTV channels. Compared to the traditional time-frequency (TF) domain multi-carrier (MC) modulation schemes such as OFDM, ODDM represents a novel delay-Doppler domain multi-carrier (DDMC) modulation scheme that can achieve superior performance in the LTV channels.
As a novel and fundamentally new waveform, ODDM or DDMC in general is still in its early stage of development. To fully unleash the potential of ODDM, challenging fundamental research problems and many practical design issues must be addressed, including practical transceiver design, channel estimation, detection techniques, and multiple-antenna and multiple-user system design. This tutorial aims at providing the state-of-the-art of this newly invented modulation scheme for researchers, graduate students and engineers to unveil its fundamentals, connections with existing MC signal waveforms, discuss recent breakthroughs, and identify major technical challenges, and new applications related to ODDM.
