| Abstract: |
| A long-range underwater acoustic information transmission technique based on Multiple Frequency Shift Keying(MFSK) modulation is studied, and the demodulation method based on spectrum estimation is introduced. The sea test results indicate that transmission of 4bit/s over 80km distance was achieved. |
