Estimation of Overspread Underwater Acoustic Channel Based on Low-Rank Matrix Recovery
Sensors, 2019 In this paper, the estimation of overspread, i.e., doubly spread underwater acoustic (UWA) channels of strong dispersion is considered. We show that although the UWA channel dispersion causes the degeneration of channel sparsity, it leads to a low-rank ...
