Microwave transmission based online monitoring system for ocean noise

Abstract

This invention relates to the field of marine noise monitoring technology, and particularly to an online marine noise monitoring system based on microwave transmission, comprising: an environmental data acquisition module capable of simultaneously acquiring marine acoustic signals and meteorological data at each candidate node of the microwave transmission link; a channel quality prediction module capable of predicting the channel quality index of a candidate link composed of multiple candidate nodes based on the marine acoustic signals and meteorological data; a multi-hop transmission path dynamic optimization module capable of dynamically selecting the relay node combination and hop number of the candidate link, and allocating a bit error rate budget for each hop link on the selected candidate path; an adaptive transmission parameter configuration module capable of dynamically configuring the transmit power and forward error correction coding rate of the candidate path according to the predicted channel quality index and bit error rate budget; and a data transmission and model update module capable of transmitting data along the optimized path and updating the channel quality index according to the actual received signal quality.
