Modeling and Channel Estimation for Piezo-Acoustic Backscatter Assisted Underwater Acoustic Communications
文献摘要：
Relying on direct and converse piezoelec-tric effects,piezo-acoustic backscatter(PAB)technol-ogy reflects ambient acoustic signals to enable under-water backscatter communications at near-zero power,which was first realized through a prototype.In this paper,we propose a mathematical model of the PAB assisted underwater acoustic(UWA)communication,and address the sparse channel estimation problem.First,we present a five-stage backscatter process to derive the backscatter coefficient,and propose the channel model for the shallow-water communications.Then,we formulate the shallow-water acoustic chan-nel estimation problem as a sparse vector recovery one according to the compressed sensing theory,and lever-age the orthogonal matching pursuit(OMP)algorithm to obtain the channel estimator.Finally,simulation re-sults are provided to corroborate our proposed stud-ies.
