Indoor Propagation Modeling for UWB Communications Using LOD-FDTD Method

Abstract

This paper deals with electromagnetic channel modelling in typical indoor environments. We employ the sub-band locally one dimensional finite difference time domain (S-LOD-FDTD) method. We predict sub-band channel impulse responses, power delay profiles and path loss. The numerical results obtained using LOD-FDTD method is compared with the results obtained ADI-FDTD as well as with the published measured data in the literature. Numerical analysis provides the improvement of the proposed method over conventional FDTD and ADI-FDTD method for indoor propagation modeling.
