Sparse channel estimation for multicarrier underwater acoustic communication : from subspace methods to compressed sensing Berger, Christian R.; Zhou, Shengli; Preisig, James C.; Willett, Peter (IEEE, 2009-10-29)In this paper, we investigate various channel estimators that exploit channel sparsity in the time and/or Doppler domain for a multicarrier underwater acoustic system. We use a path-based channel model, where the channel ...
Physically constrained maximum likelihood (PCML) mode filtering and its application as a pre-processing method for underwater acoustic communication Papp, Joseph C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-09)Mode filtering is most commonly implemented using the sampled mode shape or pseudoinverse algorithms. Buck et al placed these techniques in the context of a broader maximum a posteriori (MAP) framework. However, the MAP ...
