Comparative Study of Radio Channel Propagation Characteristics for 3G/4G Communication Systems

چکیده
A propagation model for 3G/4G communication systems is considered in this paper. The analysis method is based on high frequency ray-tracing and the uniform theory of diffraction. The ray contributions includes diffraction from building edges, reflection from the ground and building and the direct wave. According to the elevation angle of the impinging signal, different propagation components will be presented in the composite received signal. We compared propagation characteristics in 3G/4G communication systems using the above analysis method. The dependency of radio wave propagation with the geometry of the scenario and the frequency band is investigated in detail. The numerical results can be applied in cell planning of new cellular systems.
