The Probe Into Reflection Model of Large-Scale Fading

Reflection is one of the three basic factors which impact a mobile communication system. Reflection occurs when the electromagnetic wave meets an object that is much larger than the wavelength of electromagnetic wave. Received power (or its reciprocal, path loss) is generally the most important parameter predicted by large-scale propagation models based on the physics of reflection. We in this paper deduce a conclusion which is different from the authority publishings. The trigonometric vectors resultant vector E TOT (d), the received power can be come out.
