The demand for the use of a high data rate in underwater communications is rapidly increasing yet the wide bandwidth is frequently considered since acoustic signals in the underwater environment has distance dependent bandwidth. However, numerous applications which require a relatively shorter communication range such as under 2 km are able to use a wide bandwidth for high data rate. Therefore, this paper aims to survey acoustic channels using a 20 kHz wide bandwidth in East Sea, south Korea to evaluate the quality of wideband transmissions. For this channel analysis, a two-second duration frame is designed, which includes OFDM signals for data transmission, LFM for time synchronization and Zadoff-Chu sequence for checking decoding parameters. Frames are transmitted and decoded in different distances up to 2 km between Tx and Rx and the experiment results demonstrate that the wideband acoustic channels are greatly affected by the transmission distances.
