Multiscreen difraction PLmsd due to N+1 buildings replaced by equivalente N+1 absorving screen is quantized as 20log10(|Q(N+1,gc)|).
Wb: distance between buildings;
Ws: street width;
ht: tx antenna heigth;
hb: mean building height;
N+1: Number of buildings before receiver;
f: frequency (MHz);
hr: receiver antenna heigth;
pws: ratio d/ws*100 (%) due to distance d of receiver from last screen, related to...
