Orthogonal Delay-Doppler Division Multiplexing Modulation [PDF]

IEEE Transactions on Wireless Communications, 2022
Inspired by the orthogonal time frequency space (OTFS) modulation, in this paper, we consider designing a multicarrier (MC) modulation on delay-Doppler (DD) plane, to couple the modulated signal with a doubly-selective channel having DD resolutions.
