On the Time-Frequency Localization Characteristics of the Delay-Doppler Plane Orthogonal Pulse
Akram Shafie, Jinhong Yuan, Nan Yang +1
In this work, we study the time-frequency (TF) localization characteristics of the prototype pulse of orthogonal delay-Doppler (DD) division multiplexing modulation, namely, the DD…
Channel Spreading Function-Inspired Channel Transfer Function Estimation for OFDM Systems with High-Mobility
Yiyan Ma, Bo Ai, Guoyu Ma +7
In this letter, we propose a novel channel transfer function (CTF) estimation approach for orthogonal frequency division multiplexing (OFDM) systems in high-mobility scenarios, tha…
Off-grid Channel Estimation for Orthogonal Delay-Doppler Division Multiplexing Using Grid Refinement and Adjustment
Yaru Shan, Akram Shafie, Jinhong Yuan +1
Orthogonal delay-Doppler (DD) division multiplexing (ODDM) has been recently proposed as a promising multicarrier modulation scheme to tackle Doppler spread in high-mobility enviro…
On the Coexistence of OTFS Modulation with OFDM-based Communication Systems
Akram Shafie, Jinhong Yuan, Paul Fitzpatrick +2
We investigate the coexistence of orthogonal time-frequency space (OTFS) modulation with current fourth- and fifth-generation (4G/5G) communication systems that primarily use ortho…
