Abstract(in Japanese) (See Japanese page)
Abstract(in English) We report a multi-input RNN model that predicts path loss after 5 seconds using GRU (Gated Recurrent Unit), which is one of RNN (Recurrent Neural Network), as deep learning. As the input information for the multi-input RNN model, we use the time-series data of the latest path loss of the mobile terminal, the surrounding building information of the current position, and the surrounding building information of the prediction target position. The training data and validation data are the path loss measured in Yokosuka City, Kanagawa Prefecture, and the measurement frequencies are 2.2 GHz, 4.7 GHz, and 26.4 GHz. With the proposed model, the RMSE of the prediction results for the validation data was 3.6 dB, 3.8 dB, and 3.7 dB at 2.2 GHz, 4.7 GHz, and 26.4 GHz, respectively. The proposed model can improve the prediction accuracy compared to DNN (deep neural network) model using only building information and the RNN model using only the latest path loss.
