| Resumo: | The aim of this work is to study the performance of modern modulation and
multiplexing techniques over submarine acoustic channel. Initially, what is underwater
communication and its existing forms of communication is introduced. Then, the main
effects that a submarine channel is subject and their respective formulations are presented,
as well as the set of models well accepted by the academy, Bellhop models. The work is
based on the proposal to use the OFDM and GFDM waveforms as an alternative to the
classical waveform used in submarine communications, the FSK. A link simulator was
developed and, through it, value-added analyzes are presented for different waveform
configurations and channels implemented. Performance is accessed through bit error rate
(BER) curves for various levels of Eb/N0. Finally, the work produced and its perspectives
are presented, elucidating the conformity between the simulation and the theoretical
curves, as well as the challenging work that is to transmit in high rate of transmission
in the submarine channel. |
