Propagation prediction is very important in the design of wireless communication systems. A combined ray tracing and Finite Difference Time Domain (FDTD) method is improved on modeling the indoor radio propagation by applying Perfectly Matched Layer (PML) Absorbing Boundary Conditions (ABCs) to FDTD grid. Thus, more accurate propagation prediction can be obtained.
