WebSep 17, 2015 · The multipath spread in underwater acoustic channels is severe and, therefore, when the symbol rate of the time reversal (TR) acoustic communication using single-carrier (SC) modulation is high, the large intersymbol interference (ISI) span caused by multipath reduces the performance of the TR process and needs to be removed using the … WebOct 1, 2008 · Time-reversal acoustics.

WebDec 4, 1995 · We report the first experiments showing the reversibility of transient acoustic waves through high-order multiple scattering by means of an acoustic time-reversal mirror. A point source generates a pulse which scatters through 2000 steel rods immersed in water. The time-reversed waves are found to converge to their source and recover their original … WebJun 1, 2024 · Temporal compressions observed after time reversal may lead to applications to acoustic transmission in ocean acoustics (Philippe and Fink, 2000). The receiver in a time-reversal communication system does not require spatial diversity, i.e., an array of receiving sensors.
