Abstract

Classical theories such as the uniform theory of diffraction (UTD) use analytical expressions for diffraction coefficients. These methods are convenient for canonical problems and objects much greater than the wavelength and enable to rise in frequency. For more complex and smaller scattering structures, rigorous methods like the finite difference time domain method (FDTD) is more adapted. In this paper, we present an original approach, combining the advantages of these two methods. This hybrid channel modelling is finally used to evaluate the BER in a Wifi transmission.
