Title:
UNDERWATER WIRELESS COMMUNICATION DEVICE AND METHOD
Document Type and Number:
Japanese Patent JP2023109030
Kind Code:
A
Abstract:
To provide an underwater wireless communication device and method capable of suppressing degradation of communication quality due to multipath waves.SOLUTION: An underwater wireless communication device 10 provided in a mobile body 2 capable of moving on or in water and performing underwater wireless communication using acoustic signals includes a wave transmission unit 30 that transmits an acoustic signal to the other party's underwater wireless communication device, a wave receiving unit 40 that receives an acoustic signal from the other party's underwater wireless communication device, and an acoustic communication control unit 20 that controls the wave transmission unit and the wave receiving unit, and the acoustic communication control unit includes a transmission timing control unit 21 that controls a transmission time and a transmission interval of signals transmitted from the wave transmission unit. The transmission timing control unit controls the transmission time and the transmission interval such that the influence of the deterioration of communication quality due to multipath waves in the wave receiving unit of the other party's underwater wireless communication device is less than or equal to a predetermined value.SELECTED DRAWING: Figure 1
