Query: Fading Model Deviation in The NLOS Communication Channel in Limited
  Reflection   Statistical models are employed to characterize the clutter in the radar and
the reflective signals of the telecommunication receivers. End to this,
Rayliegh distribution is the simplest fading models in NLOS channels possessing
low-accuracy in the high-resolution radars and distant telecommunication
receivers. At present, high accuracy models such as the m-type Nakagami and
hybrid GG distributions are utilized in order to model fading. However, despite
the Non-Rayliegh models have better precision in the NLOS relative to the
Rayliegh models, the accuracy of these models decreases when the radiation
angle in the transmitter and the reflection angle in the receiver are
different. In this paper, the K distribution function is analytically
introduced and deployed to model the fading using practical data. Although this
model was previously introduced to describe the clutter properties of the radar
