Low-Power Microcontroller-based Acoustic Modem for Underwater Robot Communication
This paper presents a low-power microcontroller-based acoustic modem for low-range communication based on aspects of whale and dolphin communication. The approach is to decrease influences by using a frequency shift keying (FSK) modulation combined with frequency hopping spread spectrum (FHSS). Addressing individual recipients (unicast) as well as a group (multicast) or all recipients (broadcas...
متن کاملA High Speed Underwater Acoustic Modem for Video Communication
A novel high speed OFDM based underwater modem with phase coherent modulation has been proposed for video communications. The key to achieve this objective is passband sampling, which enables us to perform coherent detection with precise control over the carrier phase by using digital carriers. Currently commercially available long-range underwater mo-dems provide a maximum data rate of 38 kbps...
متن کاملAdvanced Signal Processing Techniques for Underwater Acoustic Communication Networks
In this thesis, we develop and investigate novel signal processing techniques for underwater acoustic communication networks. Underwater acoustic channels differ from radio communication channels in the lower speed of signal propagation, richer and often sparse multipath arrivals, and more severe Doppler effect. Therefore, many signal processing techniques developed for radio communications may...

متن کاملShort Paper: The Softwater Modem – A Software Modem for Underwater Acoustic Communication
The Softwater Modem is a software modem for underwater acoustic communication that enables users to run applications on the familiar sockets interface without any additional hardware except for transducers and associated amplification. A standard TCP or UDP transport protocol runs on top of IP, which via the Linux TUN driver, runs on top of custom datalink and PHY layers tailored specifically t...
