(6)分别用Azimuth1~Azimuth6减去每个小区的方位角,如果结果小于0则加上360,得到Azimuth1’~Azimuth6’。(6) The azimuth angle of each cell is subtracted from Azimuth1 to Azimuth6, respectively. If the result is less than 0, 360 is added to obtain Azimuth1'~Azimuth6'.
(7)将Azimuth1’~Azimuth6’分别代入到天线损耗数据文件中的HorizontalDegree,计算出HorizontalLoss1~HorizontalLoss6。(7) Calculate HorizontalLoss1 to HorizontalLoss6 by substituting Azimuth1' to Azimuth6' into HorizontalDegree in the antenna loss data file.
(8)根据以上已经得到的信息,分别计算每个小区的pathloss:(8) Calculate the pathloss of each cell based on the information obtained above:
pathloss=-RIP-44.9*log(D)-13.82*Log(H)-6.55*Log(H)*Log(D)-HorizontalLoss,这样每个点得到6个pathloss的值,分别为pathloss1~pathloss6。Pathloss=-RIP-44.9*log(D)-13.82*Log(H)-6.55*Log(H)*Log(D)-HorizontalLoss, so that each point gets 6 pathloss values, pathloss1~pathloss6.

(11)得到所有小区的干扰位置数据,最后结果可能会有重复的情况,因为一个干扰源会干扰多个小区,因此最后结果,对于同一个3公里以内的相同的连续干扰RB,只显示一行记录。干扰结果展示如表2:(11) Obtain the interference location data of all cells, and the final result may be repeated, because one interference source may interfere with multiple cells, so the final result shows only one row for the same continuous interference RB within the same 3 km. recording.
