The application of a virtual time reversal mirror to upstream communication of underwater acoustic networks
摘要
Abstract
Based on the properties of an underwater acoustic channel, using the uncorrelated character among different users' channel impulse responses ( CIR), the single-element virtual time reversal mirror (VTRM) was proposed for application to upstream communication of underwater acoustic networks. The scheme focused on information from desired users and suppressed information from undesired users; in addition, the VTRM mitigated the intersymbol interference caused by a multipath channel and improved the SNR. The simulation results show that a single-element VTRM can separate every user's information as the channel impulse responses (CIR) are uncorrelated,which works favorably toward realizing underwater acoustic networks.关键词
