... include the complex reflection coefficient ofthe surface, the antenna gain in the direction of the reflected path, and path attenuation .The time dependence of Γ(t) andξ(t) is due to the fact that all of ... is due to the fact that all of these properties, aswell as the location of the reflection point, change as either the transmitter or receivermoves. The amplitude of the diffuse component, ξ(t) is ... reach the next adjacent antenna. The propagation time is (dsin θ)/c, where c is the speedof propagation. Therefore, to maximize the desired signal, the output should be:y(t) =x0(t) + ej2πdsin θ/cx1(t)...
