| dc.description.abstract | In underwater acoustic environment, inter-symbol interference(ISI) caused by multipath propagation and crosstalk between transmitters in Multiple Input Multiple Output(MIMO) communications result in distortion of signal. Time-reversal(TR), either active or passive, exploiting spatial diversity to achieve spatial and temporal focusing suppresses both ISI and crosstalk. This thesis presents the performance of communication derived by applying the passive TR and a comparison of the performance of communication between simulated signal data using VirTEX(Virtual Time-series Experiment) and at-sea experimental signal data. Consequently, VirTEX simulator can be useful as a simulator for evaluating the performance of communication system in MIMO communication. | - |
