- In this paper we present a conception of an embedded acoustic modem dedicated to the underwater communication. The Raspberry Pi is used as a low cost hardware platform. The solution of the physical layer consists in modulation, synchronisation, frames forming, symbol mapping, etc. Specifically, the modulation is based upon linear and hyperbolic chirp signal generation. The synchronisation is based upon the correlation of received and transmitted signals. The performance of the communication is tested by the computer simulation. The simulation is realized by USB sound cards and a wire. In the simulation, transmitted signals are intentionally degradated by the additive white gaussian noise.
