Simulation of Indoor Propagation Model Using Ray Tracing Method

One important indoor propagation model is the ray tracing method, which serves as a commonly used simulation approach. The ray tracing technique predicts signal propagation characteristics by simulating the transmission paths of rays within indoor environments. This MATLAB implementation utilizes source code to construct the simulation environment, where key algorithms include geometric optics principles for ray path calculation, reflection/diffraction modeling using Fresnel equations, and signal strength computation through path loss models. The simulation framework typically involves environment mapping, ray launching algorithms, and multipath component analysis. Through this simulation, researchers can gain deeper insights into indoor signal propagation behavior and perform relevant analysis and optimization based on simulation results. The ray tracing method therefore represents a valuable tool for studying and improving indoor propagation models, with MATLAB providing functions for 3D environment visualization, ray-path plotting, and received power calculation.
