An Overview of Millimeter Wave Massive MIMO Technology and Marine Rain Attenuation Models

When millimeter wave(MMW) massive multiple-input multiple-output(MIMO) is applied in the marine communication,it can provide higher transmission rate and more communication services than the traditional marine communication.The rain attenuation can not be ignored when the communication base station based on MMW massive MIMO is used for marine communication.A rain attenuation prediction model with good prediction performance is the key to consider the rainfall problem.This paper expounds and analyzes the relevant principles and research status at home and abroad from four aspects of rain attenuation model,massive MIMO technology,MMW communication,and radio wave attenuation characteristics at sea,and summarizes the technical features and future development trend of the combination of the four aspects with rain attenuation.It provides a theoretical reference for the application of rain attenuation model in MMW massive MIMO communication.
