N2 - This article presents the results of a frequency offset compensation method applied to a vertical underwater acoustic communication system based on orthogonal frequency division multiplexing (OFDM). The communication link is established between the research submersible SHINKAI 6500 and a surface platform. The frequency offset compensation method utilizes a set of hypothesized frequency offsets and proceeds to detect the data symbols by using either coherent detection, which requires additional channel estimation, or differentially coherent detection, which relies on the frequency coherence between the OFDM carriers. Using the SHINKAI experimental data transmitted in the 16 kHz-24 kHz acoustic band over a 1.4 km deep-water vertical channel, we assess the system performance in terms of data detection squared error (SE) and demonstrate that the proposed method provides excellent performance results.
