Abstract:

A propagation model calibration method based on propagation environment classification was presented, which took advantages of the information obtained from digital maps. Experiments and simulation results show that the inappropriate application of calibrated propagation models leads to larger errors of path loss prediction, with a mean error around 30?dB. While with the proposed method, the accuracy of path loss prediction could be improved with the mean error decreasing 6?dB to 30dB.
