Title:
METHOD, APPARATUS AND DEVICE FOR GENERATING UNDERWATER ACOUSTIC COMMUNICATION AND DETECTION SIGNAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/110410
Kind Code:
A1
Abstract:
Disclosed are a method, apparatus and device for generating an underwater acoustic communication and detection signal, and a storage medium. In the prior art, underwater detection and underwater communication are separately designed and used as independent devices, and different signals are respectively used for underwater communication and underwater detection. The method in the present application comprises: acquiring an initial OFDM communication signal and a preamble sequence; generating a single-frequency signal corresponding to the initial OFDM communication signal; and adding the preamble sequence and the single-frequency signal to the initial OFDM communication signal, so as to generate an integrated communication and detection signal. Therefore, underwater communication can be performed between communication nodes by means of an integrated communication and detection signal, and an underwater object within the coverage ranges of the communication nodes can also be detected, so as to achieve the effect of integrating underwater acoustic communication and detection.
