Low-Complexity Channel Estimation for OTFS via Coordinate Descent Exploiting Delay-Domain Sparsity
IEEE Open Journal of the Communications SocietyOrthogonal time frequency space (OTFS) modulation has attracted considerable attention for high-mobility wireless communications; however, accurate channel estimation (CE) remains challenging in the presence of fractional Doppler shifts.

Parallel Coding for Orthogonal Delay-Doppler Division Multiplexing
IEEE Transactions on CommunicationsThis paper proposes a novel parallel coding transmission strategy and an iterative detection and decoding receiver signal processing technique for orthogonal delay-Doppler division multiplexing (ODDM) modulation. Specifically, the proposed approach employs a parallel channel encoding (PCE) scheme that consists of multiple short-length codewords for ...

From conventional to delay/Doppler altimetry
De l'altimétrie conventionnelle à l'altimétrie SAR/Doppler Depuis plus de vingt ans, les altimètres classiques comme Topex, Poseidon-2 ou Poséidon-3, ont fourni des formes d'onde qui sont utilisées pour estimer de nombreux paramètres tels que la distance entre le satellite et la scène observée, la hauteur des vagues et la vitesse du ...
