Abstract: In this paper, we propose a novel waveform index modulation orthogonal frequency-division multiplexing (WIM-OFDM) scheme to increase spectral efficiency for multicarrier systems. More ...
In Iran, not only mobile and fixed networks are jammed, but also Starlink. We explain how this is likely achieved despite ...
Abstract: This paper investigates channel estimation for linear time-varying (LTV) wireless channels under double sparsity, i.e., sparsity in both the delay and Doppler domains. An on-grid ...
