I. INTRODUCTION
Orthogonal Frequency Division Multiplexing (OFDM) is
a wideband modulation scheme that has recently gained at-
tention for underwater acoustic communications. The benefits
of OFDM include its ability to overcome long channel delay
spreads through the use of a guard interval, its ability to trans-
form a frequency selective channel into multiple frequency
non-selective channels, and its relatively easy implementation
through the use of the fast fourier transform and its inverse.
