To improve the spectrum efficiency and reduce the energy attenuation in the propagation process,it is important to establish an efficient signal propagation model to predict the propagation path and the signal strength at the receiver.Aim at the microcellular environment,a two-dimensional ray tracing model based on the incident and rebound ray methods was established,with the signal propagation characteristics of different combinations of emitters and receivers were analyzed by the model in this environment.The results show that distances of different combinations and microcellular environment jointly affect the number of propagation paths of the signal.More propagation paths and less signal loss are achieved in the condition of a close-distance combined position with better reflection environment.The research results can guide network planning and construction in the microcellular environment.
