Abstract :
We simulated time reversal communication with using simple ray theory. Assuming equable temperature and a static water tank, we geometrically calculated the multipath waves with using Pythagorean Theorem. We simulated both time reversal and general BPSK communication by using 10 kHz bandwidth. The result shows this simulation is available for time reversal simulation under the specified situation. The result also shows time reversal communication has fewer errors than general communication.
