| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Underwater acoustic communication (UAC) is used for data collection and remote control in autonomous underwater vehicles (AUVs). Communication performance is strongly affected by multipath and Doppler shift depending on communication environment. These countermeasures are indispensable for stable communication. This paper describes the countermeasures against long delay multipath and Doppler shift in UAC, where their effectiveness has been reported by our experiment in harbor. In multipath test, single carrier frequency domain equalization (SC-FDE) has provided better communication performance than OFDM as far as QSPK transmission. In Doppler shift test, we have confirmed the effectiveness of parallel resampling that can cope with Doppler shift dispersion. | |
