Abstract: Abstract: This paper proposes a filter bank multicarrier (FBMC)-based
underwater transmission scheme for voice and image signals.
In this scheme, FBMC transmission technology, low-density
parity-check (LDPC) channel coding, adaptive binary phase shift
keying (BPSK) modulation or offset quadrature amplitude modulation
(OQAM), and a power assignment mechanism are integrated
into an underwater voice and image transmission system.
The bit error rates (BERs) of voice and image signals for underwater
transmission are required to be less than 10-3, and 10-4,
respectively. The BER performances of the proposed scheme
in an underwater acoustic channel were demonstrated through
simulations, and the power saving ratios for the underwater
transmissions of voice and image signals were explored. The
simulation results show that the proposed underwater transmission
system can achieve a lower transmission-power consumption
or a higher transmission data rates compared to a system
without the power assignment mechanism. The results also indicate
that the proposed system can be used for advanced underwater
signal transmissions.
