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 کاملReview Article: Multicarrier Communication for Underwater Acoustic Channel
In past decades, there has been a growing interest in the discussion and study of using underwater acoustic channel as the physical layer for communication systems, ranging from point-to-point communications to underwater multicarrier modulation networks. A series of review papers were already available to provide a history of the development of the field until the end of the last decade. In th...

متن کاملLow probability of detection underwater acoustic communications using direct-sequence spread spectrum.
Direct-sequence spread spectrum is used for underwater acoustic communications between nodes, at least one of which is moving. At-sea data show that the phase change due to source motion is significant: The differential phase between two adjacent symbols is often larger than the phase difference between symbols. This poses a challenge to phase-detection based receiver algorithms when the source...
متن کاملAn Ultrasonic Sensor Based Low-Power Acoustic Modem for Underwater Communication in Underwater Wireless Sensor Networks
Applications of underwater sensor networks involve environmental monitoring, disaster prevention, and resource detection. As the importance of these applications has recently grown, underwater sensor networks made up of sensor nodes have to be further investigated. However, little research has been performed to develop an underwater sensor node with communication functionality. In an underwater...
