“…It is noted that the neither method does not specify how to chose significant knife-edges from the terrain elevation data. To solve this problem, an original selection procedure has been developed that accounts for both the width and the depth of the valleys between local terrain maxima considered as potential knife-edges [7]. Since accounting for too many maxima leads to gross overestimation of the losses, a flexible selection criterion has been introduced.…”

“…The calculation of the coverage probability is split into three parts: calculation of the useful sum field strength, calculation of the interfering sum field strength and evaluation of the coverage probability. For the first two parts, to perform the summation of wanted and unwanted field strengths, several approaches have been reported in the literature [7]. The location variation of field strength is modelled by a log-normal distribution with a standard deviation of 5.5 dB.…”
