Abstract :
This paper presents a spatial fading emulator dedicated to the evaluation of signals at antennas in land-based mobile communication systems under multipath fading environments. Rayleigh and Nakagami-Rice distributions are achieved by controlling the phase and amplitude of waves radiated from the scatterers that are used to form the fading emulator. Evaluation of the performance of handset antennas in realistic situations (e.g. talking) under multipath propagation environments can now be expected.
