Estimation of Overspread Underwater Acoustic Channel Based on Low-Rank Matrix Recovery
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 structure especially when the channel delay-Dop...
