%X In this paper, a novel splitting technique of ray tubes based on ray tracing method is put forward, which is called the deterministic splitting method of ray tubes. At the same time, the analytic splitting format and the demonstration of self-contained characteristic is provided. The simulation results prove that the proposed method possesses the merits of less CPU time and higher computing efficiency, compared with two known methods of ray tubes on the condition of same prediction precision. The prediction of received power has been done with this method in indoor environment. A good agreement is achieved between the simulated results and the published results.
