Thank you Pokemon.

You are right for shorting R1 but R1 cannot be equal to R2 because of :
. In R1, the distance is (dR-dx) but in R2, the distance is only (dR).
. No relationship between a, a', b, b', c, and c' because a, b, and c are the coefficient
of the Roof-to-Ground pathloss model and a', b', and c' are the coefficient of
Roof-to-Roof pathloss model. No correlation between these two model.

I used try as what you suggest but the problem is that I cannot expend the term (dR-dx)^b
since b is unknow at the time of simplifying the formular( but is know during numerican application), and b is not an integer number (as I mentioned before).

I also used try to put log10 to eliminate 10 power... but cannot be done. I will try it again today.

Thank for taking care of me.
Best regards.
