Indoor propagation modeling for UWB communications using LODFDTD method

This paper deals with electromagnetic channel modelling in typical indoor environments. We employ the subband locally one dimensional finite difference time domain (SLOD-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.
