Preliminary investigation of power delay profile computation from full wave frequency domain indoor propagation model

New developments in energy efficient wireless communications systems and indoor location and tracking algorithms have created a greater demand for accurate propagation models. In this paper a frequency domain full wave propagation model is used to produce accurate power delay profile information. The propagation model is based on the volume electric field integral equation (VEFIE). The VEFIE is solved in two dimensions at a number of frequencies and the fourier transform is applied to convert the frequency domain data to the time domain. The generated PDP is compared against the well known theory of geometrical optics and a very good agreement is achieved. The effects of finite bandwidth and resolution on the PDPs are also investigated.
