Excess path length
WebLOS path at the receiver. This process repeats, giving us alternating Fresnel zones that provide constructive and destructive interference to the total received signal every =2 increase in h. We de ne the set of points at which propagation produces an excess path length of precisely n =2 to be called the nth Fresnel zone. Figure 7: Fresnel zone ... WebAssuming h < d and h >> d 1, d 2, then the difference between the direct path and the diffracted path, called the excess path length Δ can be found as: To find path difference Δ: The simplified model is given as, Figure 8: Simplified model to find path difference Path difference = ( p 1 + p 2) – ( d 1 + d 2) p 1 = d 1 2 + h 2 p 2 = d 2 2 + h 2
