Underwater Acoustic Communication System Based on MC-MFSK

Abstract:

For the time-space-frequency varying shallow water acoustic channel, we designed a multi-carrier FH-MFSK system, so that it can be reliably transmitted over these channels. This paper also design of a wake-up signal, and synchronization obtain information frame structure, the simulation result of the algorithm is presented. In the core of DSPC6747 chip, with class D power amplifier, we designed a reasonable layout, stable and reliable hardware circuit. By simulation, adding noise experiments, and water pool experiments verify the good performance of the system, a very low bit error rate (BER) communications were archived.
