We have researched on time-reversal communication in the deep ocean and have proposed a method of combining time reversal and adaptive equalization. In the previous at-experiments, communications at the range from 10 to 100 km were demonstrated with synthetic time-reversal array. In this experiment, passive time-reversal communication was achieved with a real receiver array to the range of 300 km first as the experiment intended for communication. Chirp signals and M-sequence signals are used as a probe signal at the data rates of 50 and 100 bps. In spite of Doppler Effect, the proposed method achieves demodulation with no error. |
