%X Time reversal is a unique self-focusing technique for spatial and temporal focusing of sound in unknown environments. Ocean is a complicated and changeable channel which may distort the signals and degrade the performance of communication system. Time reversal principle and its application to passive communication were introduced. The simulation result shows that this technology can reconstruct signal and erase intersymbol interference, so that the performance of communication system is improved.
