Title:
SIGNAL TRANSMISSION METHOD AND DEVICE IN UNDERWATER COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2018/155818
Kind Code:
A1
Abstract:
The present invention relates to underwater communication and, more specifically, to a signal transmission method and device which configure and transmit physical channel information such that low-power control is performed in underwater communication. The present invention configures the physical channel information such that a receiving node side can check through a combination of preambles whether a signal is provided to itself, when forward direction communication is performed in a centralized underwater communication network. Therefore, the present invention performs control such that only a corresponding receiving node requiring data reception performs a demodulation operation, without requiring all receiving nodes to always perform demodulation in a forward direction communication process. Through this process, many receiving nodes do not perform unnecessary demodulation operations in the forward direction communication process, thereby providing an effect of preventing unnecessary power consumption.
