抄録(和) Recent developments in the next generation of mobile communication and the application of the Internet of things has raised the need to develop more accurate channel models. This work presents the development of a supervised based machine learning (ML) prediction model for large scale channel parameters (LSCPs) estimation by analyzing the reflected multipath ray's information. The reflected rays varies with the morphology structure of the propagation environment, hence a dynamic LSCPs predictive model can be realized. The input parameters to the prediction model are transmitter (TX) and receiver (RX) positional coordinates, and the reflected rays' information such as the delay, angle of arrival, angle of departure, elevation angle of arrival, elevation angle of departure, and power gain. The proposed model was implemented using Random Forest (RF) which can predict both linear and nonlinear data. Ray tracing (RT) simulation was performed to calculate the input measurement dataset of the LSCPs, and the input information of the reflected rays. Cross validation was then utilized to validate the model.
