RESOURCE ALLOCATION METHOD AND DEVICE OF UNDERWATER ACOUSTIC COMMUNICATION SYSTEM HAVING WIRELESS ENERGY COLLECTION CAPABILITY

摘要

Disclosed in the present invention are a resource allocation method and a device of an underwater acoustic communication system having wireless energy collection capability. In said method, an underwater acoustic transducer array is provided at a backbone network base station or a central node, and a weight matrix of the underwater acoustic transducer array of the base station is optimized by means of a beamforming technology, so that an underwater acoustic signal emitted by the base station is aligned with an underwater terminal node. After an acoustic wave signal received by the underwater terminal node is converted into an electrical signal by means of the underwater acoustic transducer, a power splitter is used to separate the electrical signal into two paths of signal flows, one path of signal performing signal detection, and the other path of signal performing energy collection by means of an energy collection module, and the collected energy charges a battery of the terminal node by means of a power supply module, thereby achieving energy supplement of the terminal node. Said method obtains the maximum energy collection of a terminal node while ensuring the communication quality, thereby performing energy supplement to the terminal node of the underwater acoustic communication network to the maximum extent.
