Multiuser OTFS Channel Parameter Estimation Toward Grid-Independent Regime
Hanning Wang, Rong-Rong Chen, Arman Farhang
We study channel parameter estimation for multiuser orthogonal time frequency space (OTFS) systems in the delay-Doppler (DD) domain. To enable structured parametric estimation, we…

Windowed Dictionary Design for Delay-Aware OMP Channel Estimation under Fractional Doppler
Hanning Wang, Xiang Huang, Rong-Rong Chen +1
Delay-Doppler (DD) signal processing has emerged as a powerful tool for analyzing multipath and time-varying channel effects. Due to the inherent sparsity of the wireless channel i…
