Deterministic path loss models

WebAug 27, 2015 · In this paper, we propose the 2D semi-deterministic path loss model aiming at improving the level of realism. In this model, the mean path loss is modeled deterministically, whereas the shadow fading and small-scale fading are modeled statistically. The rest of the paper is organized as follows. WebThe Monte Carlo method is employed to estimate the path loss in the same area under different conditions, and results show that the electric wave propagation gradually degenerated from the round earth loss model to the free space model with increasing wind speed.
