  Abstract

In this paper, the maximum excess delay spread is obtained from the measured data obtained from the underwater acoustic communication experiment based on the OFDM system performed in March, August, and November 2017 in Taean - Gun, Chungnam. Then, coherence bandwidth was obtained and the underwater channel characteristics were analyzed according to seasonal temperature changes. As a result of the analysis, the maximum excess delay spread was longer in March when the water temperature changed significantly in the surface layer compared to the data of August and November when the water temperature was constant in both the -10dB and -15dB thresholds. As a result, it can be seen that the coherence bandwidths are relatively narrow in March when the threshold values are -10dB and -15dB, respectively, when compared with the data in August and November.
