On Modeling of a Frequency Selective Nakagami-Rice Fading Channel

抄録

In wireless systems, such as fifth-generation mobile communication (5G) and distributed antenna systems, wireless environments are assumed to be line of sight (LOS) environments. This study proposes a frequency selective Nakagami-Rice fading model by introducing the time difference between the direct wave and first delayed wave to a typical Rayleigh fading model with an exponential decay delay profile. Thus, the proposed model includes the conventional models. We derived the frequency correlation for the proposed model and demonstrated its effectiveness through a numerical evaluation of the impact of various parameters on the derived expression.
