Construction method and device of cross-sea wireless channel path loss prediction model

The invention discloses a method and a device for constructing a cross-sea wireless channel path loss prediction model. The method comprises the following steps: collecting channel path propagation loss; standardizing model training data; constructing an LSTM training network, and obtaining a channel path propagation loss prediction value through the LSTM training network; quantifying, coding and normalizing the normalized model training data obtained by measurement; classifying the quantized, coded and normalized training data; constructing a training and testing data set of the LSTM training network; optimizing hyper-parameters and network architecture parameters; and training a path loss prediction model. According to the method, the complexity and variability of the marine environment can be fully considered, the channel path loss under different environment conditions can be effectively predicted, and reliable channel prediction support is provided for operation of a marine communication system. 本发明公开了一种
