碩士 / 聖約翰科技大學 / 電子工程系碩士班 / 100 / In this paper, we use the underwater channel model is [1] for our research. We
use the Orthogonal Frequency Division Multiplexing system for the underwater
channel to improve the transmission results. There are several important features
in the warm shallow underwater channel, such as time-varying and multi-path
effects. The Doppler spread effect makes the phase drastically changes. It causes
unfavorable factors in underwater communication. In this paper, we use the
OFDM to combat multi-path and remove the delay spread which is caused by
the underwater channel. We use the equalizer to overcome underwater channel
fading which caused the distortion.
