Enhanced Urban Path Loss Prediction Model with New Correction Factors

Abstract

Modification of ITU-R P.1411 model to enhance the prediction accuracy in urban environments having variable heights of buildigns is proposed in this paper by introducing two kinds of novel correction factors. One is considering the relationship of the heighest building height and the transmitter (Tx) antenna height, and the other is considering the effect of receiver (Rx) position on crossroads. After introducing two correction factors, the prediction accuracy is shown to be improved.
