Abstract
In this paper we achieve experimental data evaluation using SSB(Single-side band) modulation in the ocean. Present research in underwater communication is applying digital modulation, OFDM(Orthogonal Frequency Division Modulation) and MIMO(Multiple Input Multiple Output) system. However, Commercial modems using analog modulation techniques in oceans. So, we achieved experimental for modem appliance development of correct high quality in South Korea sea characteristics. This experimets achievd useing SSB analog modulation in Jin-hae shore of shallow water condition. We analyzed Doppler effects, reverberation and transmission characteristics for real channel effect analysis. As a result, reverberation and ships self-noise are disturbed factors for underwater communications.
