Abstract
Performance of underwater acoustic
communication system is influenced on channel characteristic.
Especially, an important feature of the underwater acoustic
communication is multipath propagation and Doppler spread
cause by the surface and bottom reflections. In this paper, we
study the application of high speed image transmission using
multi-carrier modulation, where this capability can enable the
next generation of undersea expeditions. We use Hierarchical
Quadrature Amplitude Modulation (HQAM) as Zero-padded
(ZP) orthogonal frequency division multiplexing (OFDM)
mapper to be unequal error protection for the transmitted bit
stream. We proved capability of ZP-OFDM multi-carrier
modulation based on HQAM mapper with Reed Solomon
channel coder in sensitive bit error reduction without receiver
equalizer. Proposed scheme evaluated using different types of
images for different values of the modulation parameter and
underwater channel physical parameters.
